I can understand if older people are confused by trans issues. That seems fair. I mean, just a few decades ago, people hardly even mentioned them unless they were making a joke.
When it comes to hate, though, I’m with you. At the end of the day, these are still PEOPLE we’re talking about. If they’re doing something you don’t approve of, then just don’t do it yourself. It doesn’t get any easier than that. No hatred required.
