1) harping on the Obama birther crap for years, clearly just became a dog whistle to people who didn’t like seeing a brown president

Eh. I guess.

2) painting all Mexican immigrants as criminals and rapists

Except he hasn't done that.

3) the “good people” on both sides comment when one of those sides were literal neo-Nazis/KKK

Trump:

I do think there is blame – yes, I think there is blame on both sides.

I'm not talking about the neo-Nazis and the white nationalists, because they should be condemned totally – but you had many people in that group other than neo-Nazis and white nationalists, okay? And the press has treated them absolutely unfairly.

The following day, it looked like they had some rough, bad people, neo-Nazis, white nationalists, whatever you want to call ‘em. But you had a lot of people in that group that were there to innocently protest and very legally protest, because, you know, they had a permit.

4) claiming not to know David Duke when asked about the fact that this well known white supremacist was supporting Trump, even though Trump himself had spoken about David Duke before... and even if he did forget who it was why not disavow such support instead of deflecting the question?

First, I have to ask, who's David Duke?

and even if he did forget who it was why not disavow such support instead of deflecting the question?

asking someone to make a decision when they don't have all the information

White nationalists have been backing the GOP for years, this isn't a Trump thing. Just because white nationalists follow the GOP doesn't make the whole thing a racist naionalist hellhole. Communists back the Democrats, does that make them all Communist? No.

5) claiming Obama literally founded ISIS

Eh. I disagree that that is based on racism. I mean how many people are saying trump is literally Hitler? Horrible insults are thrown around every which way these days because of shitty partisan politics. Yeah, could've been racism, but I see reasonable doubt.
