Wallace Shawn is an actor and playwright best known for the character Vizzini in The Princess Bride.
Anyone who has seen the film will remember his famous catchphrase ("Inconceivable!"), that he says whenever something goes wrong.
Shawn also voiced the dinosaur Rex in the Toy Story films, and has acted and voiced characters in a number of television shows and films.
Unfortunately, most people are unaware of Shawn's activism directed towards harming the State of Israel.
He is on the advisory board of Jewish Voice for Peace, a rabidly anti-Israel group that tries to hide its agenda by labelling itself as a pro-Israel group that simply wants a peaceful resolution with the Palestinians.
Shawn's active participation with this organisation, as well as his past statements about the Jewish state, are truly unsettling.
Jewish Voice for Peace's ultimate goal is the destruction of the State of Israel.
While the group claims to only work actively towards boycotting the West Bank, Rebecca Vilkomerson, executive director of Jewish Voice for Peace, has said: "We do feel connected to the global BDS movement. We consider ourselves a part of it.
"We would defend the right of people to do a full boycott. This is what Palestinians are asking for, and we respect their call."
The JVP website also states: "We believe that the time-honoured, non-violent tools proposed by the BDS call provide powerful opportunities to make that vision real."
However, contrary to their assertions of non-violence, NGO Monitor wrote an investigative report on JVP, showing the group "supports or has partnered with groups such as Sabeel, Electronic Intifada, Al-Awda, International ANSWER Coalition, the International Solidarity Movement and Students for Justice in Palestine, all of which label Israel a racist apartheid state, support BDS and, in some cases, support violence against Israelis".
JVP also refuses to endorse a two-state solution and many members are against the very idea of a Jewish state.
Furthermore their website states their ultimate goal is for Israel to, in part, "promote the rights of Palestinian refugees to return to their homes and properties".
Anyone who knows anything about this conflict knows that calling for the right of millions of Palestinians, including members of Hamas and Islamic Jihad, to enter Israel's borders and seize properties and residences that they claim their grandparents once owned, is in essence a call for the destruction of Israel.
Judith Butler, who is on the academic advisory council of JVP, in response to a question about the relationship between Hamas and Hezbollah and the 'Left', answered: "I think, yes, understanding Hamas/Hezbollah as social movements that are progressive; that are on the left; that are part of a global left is extremely important."
With disturbing opinions such as this it is no wonder she is so strongly affiliated with JVP.
The Anti-Defamation League in 2010 identified JVP as one of the top 10 anti-Israel groups in the country.
ADL explained: "While JVP's activists try to portray themselves as Jewish critics of Israel, their ideology is nothing but a complete rejection of Israel.
"In May, 2008, for example, members of JVP protested many of the celebrations of Israel's 60th anniversary that took place around the country, essentially illustrating that they oppose Israel's very existence."
Wallace Shawn's involvement with this movement reveals his real "humanitarian" side.
He has given absurd interviews and penned columns against the Jewish state. His complete ignorance of what Israelis have been facing is glaringly obvious from his own words.
He's stated that Israel is such a racist country that Palestinians understandably see the Jews as "an enemy that can't be reasoned with, but can only be feared, hated and, if possible, killed."
He also writes that since Israel is such an immoral country "the future of the Jews looks increasingly dim".
Shawn says that the Jewish people are now viewed as the victimisers and said that "from a moral point of view it was better when we [the Jews] were victims".
Yes, in his warped sense of morality, rather than Jews trying to defend themselves against genocidal enemies like Hamas, Shawn feels the Jews were better off as they were led into Auschwitz's gas chambers.
In 2014, the ADL released a pro-Israel poster signed by a number of celebrities and Hollywood executives that featured the words of Golda Meir: "We can forgive [them] for killing our children. We cannot forgive them for forcing us to kill their children.
"We will only have peace with [them] when they love their children more than they hate us."
The ad also states that: "These haunting words of Golda Meir are as current as today's headlines. She could have been talking about Hamas."
Shawn was so incensed by this ad that he took it upon himself to pen a 'translation' of what he thought the poster was really saying.
Shawn believes that what Golda Meir was really trying to say is: "When we kill the children of Arabs, the Arabs made us do it. They hate us so much, they are so angry, that they do things that enrage us and make us kill children.
"If they were decent people who loved their children, they would set aside their hatred and stop provoking us, and we would then stop killing the children."
Shawn writes: "Golda Meir can be interpreted as saying here that she plans to kill the children of Arabs up until the moment when, in her sole judgment, the Arabs stop feeling 'hate' and become sufficiently unprovoking and pacified."
Hamas itself has said it loves death more than the Israelis love life.
Videos have shown Palestinian mothers happily blessing their bomb-strapped children prior to their suicide missions.
Hamas and members of the PA both regularly incite the population with calls for terrorist attacks and the genocide of all Jews on earth (including Shawn).
The moment they stop hating the Jews to that extent, then the fighting can maybe have a chance of ending.
That Shawn would defend or legitimise Palestinian terrorism and the corrupt, murderous governments of Hamas and the PA is sickening.
It would be easy to just laugh at people like Wallace Shawn if it wasn't for the fact that their very involved activism incites hatred against Israel and the Jewish people, and his actions and words give justification for the murder of Jews.
