Marco Rubio asserts that he cannot see any evidence of discriminatory actions against Muslims in America. Has he not heard of the internet? It has been full of news stories about random people are perceived to look like Muslims being targeted for harassment as you can see here, here, and here.
Chris Hayes gives one example of how right-wing media have been fanning the flames of anti-Muslim hysteria, similar to the way other groups (like Jews and Catholics) were vilified in the past.
Larry Wilmore helps Rubio out though I suspect that Rubio knows full well what is going on but is simply feigning ignorance. In this montage, Wilmore shows a clip with a white man calmly walking down a street following a Muslim woman, his face covered with a mask and carrying an assault weapon. How can it be that this is now considered acceptable behavior? Imagine if the person with the weapon had been black or dressed in a way that suggested non-Christian beliefs?
