Uh, that would be your opinion, and not to be confused with "truth".
Find the evidence stating Dorner's political leanings, not that it's relevant to the conversation or anything. I have no idea why you even referenced him.
You certainly didn't look very hard for reference to Mr Dorner's politics
The second hit on Google using the terms chris dorner politics pointed to a Van Jones article at CNN warning us not to discuss Dorner's politics. That would be a sure sign to anyone remotely familiar to Mr Jones, what Dorner's political views were. (reading it confirms my first reaction)
Now, the fact that you were unable to discern his political affiliation confuses the shit out of me. There are several explanations.
1. You are lazy and didn't actually look for an indication of Dorner's politics.
2. You are intellectually incapable of performing a simple Google search
OR
3. You're a damned liar. You knew about his insane racist rantings and it simply did not fit your position.
Which is it?
