Yeah, I agree. I'm not a conservative, but if I were I wouldn't want Kanye (or Trump) to be the one championing my views. Find someone who (1) actually has conservative views, (2) isn't mentally ill, and (3) can articulate those views persuasively. Thomas Sowell might be considered a good example.

Obviously no one is arguing that we should attack mentally ill people. We can acknowledge that mental illness impairs decision making ability without attacking people. It doesn't even mean that people can't agree with some of Kanye's conclusions, but if you are such a person, consider finding a champion for your ideas who can do a better job of articulating those ideas.
