It's already been said enough times but I'll do it once more anyway:
Ignore the idiots, there are so many who feel safe behind their monitor because they cannot be seen or reached by anyone else. Some pimple covered kid who has his lunch money stolen from him every day in school thinks he can be Conan the Barbarian in the great anonymous world we call the internet.
They're like dogs, the little pesky ones are always the ones yapping round your feet and pissing you off. The big ones that could eat them in one gulp stay quiet and respectful. They have nothing to prove.
Ignore them. They ain't worth it.
