“Racism” can be judged by either a psychological condition, or by behaviors. The former seems dubious to me, for I think obvious reasons. Voting for Trump entails supporting ideas and policy proposals that will have disproportionately harmful effects on minorities. Furthermore, Trump is explicitly racist. Hence, voting for Trump is straightforwardly racist behavior. The upshot of this is that, if you’re supporting Trump, you’re just not a very good human being, and you really ought to step back and reconsider your life and your values. Trump is running the most ugly and immoral campaign in recent memory. There simply isn’t a good reason for supporting him that doesn’t entail moral failure.
I say this as someone who has been defending Trump voters in other contexts (I think both the left and the right have quite a bit of soul searching to do). For example, I’ve said elsewhere, to a group of leftists:
"A lot of the narrative around Trump is that his candidacy demonstrates that America is in big trouble because it allegedly shows how stupid people are. It’s actually worse than that. America is in big trouble because, for the segment of the population supporting him, Trump is the economically rational choice. That is, if you’re a working class strait white without a college degree, and you’re looking around at the choices, selecting Trump is fairly rational. For one, Trump is the only person saying to those uneducated working class whites that he’s their man. When large portions of the left have essentially turned “strait white male” into a pejorative, what does the left have to offer working class whites exactly? A chance for noble self-sacrifice? Good luck selling that as a political strategy.
The left is correct to critique Trump’s supporters as racist and xenophobic; they are both of these things. But this isn’t the only, or even the main, reason they are supporting him. They’re supporting him because he’s speaking to their rational economic self-interest. And at the end of the day, this is what the vast majority of people cast votes for."
