Why do democrats call everyone a racist ?

Name calling is rhetorical technique used to try to win arguments. It's not a very good technique because it doesn't really address the issue(s) at hand; it's just a way to try to discredit the other side. When someone starts calling you names it usually means they don't have any facts to use against you.

It's appears to be a tactic used to blame anyone that opposes them and their ideas. It's a strategy used to get sympathy for their cause by calling their opposition 'racist'. That means that if you oppose the lame brain ideas of the current occupant of the Oval Offices ideas you're a 'racist'.

democrats can't argue with facts so that leaves them with rhetoric.

your premise is false

I am a Democrat. I don't think someone is racist unless they are against Obama because he is black or they make derogatory remarks about black people in general. Stick to the issues and I, along with any other thinking and rational person, have no reason to suspect that anyone is racist - Republican OR Democrat.

And because I was raised to have manners I wouldn't dream of calling anyone a racist even if I thought they were because it's rude. I once had dear friends who were in their 80s and it wasn't until Obama ran for President that I found out just how racist they were. I couldn't stand listening to them talk about blacks (which they had never done before) and it destroyed our friendship. Even so, I didn't argue with them or call them names. What's the point? They certainly weren't going to change their views because of anything I would have to say to them. And the same thing goes for any other person who is racist.

When you go around calling people racist you are at the same time declaring you are not even though you are. It is kind of like saying my daddy can beat up your daddy. Essentially they are trying to convince themselves that there are no democratic racists by calling everyone else on it.

Because suspicion always haunts the guilty mind, and they find it disconcerting that they don't have the right to make up their own facts.

Stereotyping is a very serious error in thinking.
