Pretty much every single question asked on here will have a nasty answer somewhere, usually by people who never ask any questions. Easier said than done sometimes but just ignore 'em, don't feed 'em.
Your basically asking how to deal with trolls. My advice if to always ignore them since any recognition you give them counts as a win in their twisted minds and will only encourage them to continue their childish behavior.
Ignore them. And if they continue to bother you then just block them.
I think most trolls can easily get around being blocked by creating new accounts. Since their whole motivation is to get attention, ignoring them is the best action.
Get into there head and reprogram them to think my way :)
