Whether Trump was a bigot or not they'd still call him one. They always do. It's like the boy that cried wolf. Tim Tebow could run for president and they'd call him a bigot. The hypocrisy of it is amusing, but I'm sure that's lost on the liberals. They are dead serious.
If you are any kind of normal person, as opposed to a politician, and just say what you think, you are going to get reemed by the press because they are going to play pattycake with what you said. We've been trained to expect these politicians to be so benign in their speech that they essentially say nothing. Trump doesn't want to be that kind of candidate, so he's blunt, which shocks people who expect politicians to be wind-up toys who mouth talking points. Anyone who doesn't is considered crazy and dangerous. And they are, to the status quo, that is.
In several cases I've seen, Trump was purposefully taken out of context. Once that starts, and people buy it, then it snowballs because most have jumped on the bandwagon and few check the facts, and it becomes a lynch mob. The fact that he's a Republican just makes it worse because liberals LOVE to accuse Republicans of being bigots.
I'm not saying he hasn't put his foot in his mouth some. I'm saying it's overblown.
