The American ISIS (KKK, ultra religious abortion clinic bombers), alt-right racists/sexists/xenophobes would take over if Trump wins, or at least would try. Good thing that won't happen.
First, I despise Trump, but the notion that the KKK will "take over" if Trump wins is absolutely absurd. I was not aware that KKK members were on the ticket, running for Congress, or would be prominent members of Trump's cabinet. And of course, it goes without saying that those groups, as despicable as they are, are not the ones committing numerous terrorist acts around the world, chopping people's heads off, burning them, throwing gays off rooftops, and so much more.
Radical Islam is the greatest existential threat to the West since Nazi Germany.
