DO IT FAGGOT is a phrase meant to provoke a response. In 4chan the word faggot is used on anyone regardless of sexuality.

As Wimbleflat said, it not meant to be offensive.
…or maybe it is sometimes but it's been so (intentionally) overused, that thw word has lost much of its power, at least on internet forums.
That said, there is a more 'pony' alternative!
