They may catch you off guard. Or confuse you. Or shock you with their bravado.
But anyone who wants to pick a fight with you or your business in the public arena of cyberspace (Facebook, Twitter, etc.) is just a troll.
So remember this:
In real public arenas, trolls don’t sound so tough. And in reality, they aren’t actually that mad at you, if at all.
It’s just that misery loves company.
So either join the misery by fighting or happily let them be lonely by not.
