It hasn't changed my opinion of him.
I've always thought him to be a scumbag piece of crap going back 30+ years. I've never been able to stomach the SOB, even less so now that the media whore is in our faces 24/7.
But I never really thought him to be as racist as people claimed him to be, albeit the garbage that's come out of his mouth over the years brings that to question sometimes.
This time is different though and it has cemented my doubts about his racist viewpoints. The trope he spewed out on Twitter can only come from a deep inbred type of prejudice that usually only surfaces in someone when they're under the influence of alcohol or in a heated argument (aka: temporarily losing control of their faculties).
The fact that he said this crap so casually, so soberly, and so matter-of-factly for the whole world to see, now proves his racist beliefs and shows everyone his true colours beyond a shadow of doubt.
Simply put: What I wasn't so sure of before, I am sure of now.
