I think you just have to accept the fact that some people are going to choose to behave badly. The troll that stirred things up over the past couple of days was not just behaving like a little child, it was more like a mean girl from high school. She (or he) was getting her jollies by insulting and mocking other people.
Don't get me wrong, that would have teed me off if it happened to me. But we have to remember that mean girls stop being mean when it stops working. If you ignore the trolls, they get bored and go away.
Trolls exist, just like mean girls exist. You can't control them. You can only control you. The only thing you can control is how you choose to respond to them. If you ignore them, they go away.
Honestly, when I see a troll question or comment, I just roll my eyes and move on. No reason to waste my time on it.
