Generally I like talking to people with different views.
Sometimes I HATE doing it online. Context, nuance and a lot of things don't translate.
Also, there's a lot of people that are either uninterested in learning about the topic but fervent in espousing about its merits. I used to like chatting with libertarians and I just grow tired of it with the same old discussions. So I'll just refuse to engage.
Eventually you have to think of your mental health and if you're dealing with a troll or something. It's just simply not worth your time.
