Fair enough, but its always better to try to bridge differences because in my experience a lot of people are more ignorant than malicious and get defensive when confronted, and sometimes it's better to be less confrontational, of course it depends on how extreme their views are, in this case what this dude said was obviously unacceptable but all or his base might not be equally abhorrent.

That's a dangerous line of thinking that can ironically lead to extremism and eventually fascism. People vote the way do for a variety of reasons, and all politicians are fucked in some way or another(personally I think Republicans are clearly more fucked up), I'm sure you can find untoward comments made by liberal politicians that were later forgotten, because that's how it goes unfortunately, people forget and move on, focusing more on policy/propaganda rather than some random statement a politician makes for better or worse.
