It might not be official, but it sure shows how anti-Israel Amnesty USA is. Beyond that, it uses Amnesty's name and logo, without any apparent pushback from Amnesty International, so its tweets are tacitly approved by the larger organization.
Over the past several months, Israel has experienced a terror wave where innocent civilians have been slaughtered in the streets. The victims are the sort of people that Amnesty claims to want to protect.
IOTPA has not said a word about any of these attacks.
In fact, one would need to look very hard to find any condemnations of any attacks on Israelis. The few attacks on Israelis I found were couched in terms of "but Israel is far worse." I found one condemnation of a Hamas bus bombing - in 2016.
Not only that, but when these "human rights professionals" deign to mention any criticisms by Zionists, they usually dismiss them as "hasbara smear language."
The folks at Amnesty USA are not shy about admitting that they are anti-Zionist. They just redefine it to mean "critical of Israel." But in reality it means that they oppose self-determination for the Jewish people. Which is pretty antisemitic.
The account consistently dismisses any pro-Israel viewpoint as a lie by definition - and accuse anyone who supports Israel of being trolls paid by the Israeli government. In one exchange, they wrote to a critic, "R u one of the paid trolls by #Israel? Wonder what a person's soul sells for nowadays." And "R u a paid troll perhaps?" And "Do you get paid to troll? How much do you make?"
They actually said that no one should believe a word that the Israeli government or pro-Israel people says: "Don't believe the 'hasbara' (propaganda) being spread by Israeli military and supporters. They always try to control the narrative so their statements should never be taken at face value."
They've never said this about the Palestinian Authority. Or Hamas. Only supporters of Israel are accused of being liars by definition.
Yet they insist that they aren't biased.
Judge for yourself.
