Did you see me attacking Whoopie, or trying to get her shut down or shut up? Like, say, a conservative on a college campus? Nope. You sure didn't. I'm a passionate advocate of freedom of expression.
Maher sees a big problem with race and would like to see it fixed. So, he advocates for intellectual honesty and reason to fix it. I'm with him on that.
Yes, some racists cannot be changed. Their ranks can be decreased, though.
There is a downside to any tactic, and it sure seems to me that those on both ends of the spectrum make zero (0) effort to weigh the potential risks of their tactics. For example, I have been warning since I have been on this board that there would be a pushback to PC and Identity Politics. And the presidential election of 2016 and its embolding of White Nationalism have proved me right. That's a pretty nasty downside of screaming RACIST 24/7/365.
