While I have a strong negative view on MLP fans (well just the bunch who used "everypony" and such words) calling them all Pedos is not the way to go.
As long as they keep that bullshit contained in that MLP mass thread I don't see the problem...let them act silly in there. We can just hope they don't bring it over to other threads.
You will only prove him wrong by being the better person and never, NEVER, responding to a troll. You will not enlighten anyone with more responces here.
This should never have gone on this long.
If you have a problem with moderation, bring it up to admins or Sunshine using the Contact Us page at the top right. And a final word: there is nothing wrong with My Little Pony. Anyone trolling the pony thread with this "it's for pedophiles" nonsense will be infracted.
