These aren't real world bullies. They don't like your favorite cartoon character and are, in the worst case scenario, making fun of it; that's all. Zoro (or whoever) isn't your real life, nor your self-steem, nor your tools for sane development. But maybe your analogy is appropiate, because hitting gym, getting jacked and coming back for revenge is what a teenager in second year of school would do, but not an adult (and not because of "Christian" ideas). But maybe I'm wrong and some people here aren't even adults capable of committing to create a sane community.
