I do my best not to be charmed by people who work in whatever way towards
advancing monstrous policies. Not living in DC makes that a lot easier of course, but I'm really not interested in finding out that Asshole X is actually such a nice person. Someone put this Dave Barry quote on the twitter yesterday:
A person who is nice to you, but rude to the waiter, is not a nice person.
People who exploit racism to obtain power or advocate for discrimination are not nice people, no matter how charming they are.
