At this point, I should know better: Random people on the internet do not care about facts or nuance. They want to be right. I have to be honest, I have the same issue. I find myself responding, not attempting to understand a different view point.
When personal attacks begin, either because a person is that poor at debate or because they lose their temper, why bother continuing to debate?
I’d rather have the facts on a matter than be right. If I have to eat my words, I’m comfortable with that. That being said, I prefer to know the sources of the information, and not just rely on being “told” I’m wrong.
