it's a fact it happens, but it's not like there's a shady criminal breaking into the house of every hateful person and holding a gun to their head to make them say mean things...:\
just because hate is bound to happen since it's the internet and all, doesn't mean you should add to it and be able to think it's fine...or bully someone with the "life's not fair/it's the internet/suck it up" mindset and not expect them to react in upset or bash them when or if they do.
