Lord Tony doesn't bother me that much. I guess I've always been on his good side. He's invited me to his server to see his castles and socialize multiple times. His hate for Bronies doesn't bother me considering I'm never looking through pony-related topics and I am also against Bronies. It isn't a problem if you stay away from it.
Lord Tony actually contributes to the game unlike most people that hang out in off-topic. He's released multiple add-ons and maps that are okay in my opinion.
So to sum this up, instead of leaving the game, he should just maybe leave the forums.
