The political purpose of anti-semitism is to galvanize support for a movement during times of social and political upheaval. Anti-semitism in America today is a variation on the deflection theme because it is not President Trump's administration that supports anti-semitism it is Obama's Leftist/Islamist axis legacy that is trying to depose President Trump. Obama's eight year radical socialist, anti-semitic, anti-American, pro-Muslim term encouraged Leftist/Islamist anti-semitism
The current anti-semitism in America is being fomented to solidify the Leftist/Islamist axis and deflect public attention from the movement's anti-American platform and their intention to destroy American democracy. The concurrent restrictions on freedom of speech in the United States is being instigated by the Deep State's attempt to further destabilize and destroy President Trump's government
