If you're talking about the post everyone is quoting, I don't think it's worth getting upset about. Moe is a known phenomenon originating in Japan, and there's nothing in that post that specifically calls anyone a pedophile or says everyone in Japan likes it.
I don't know what else has been posted in that thread, though.
I honestly don't think that thread is as bad as it can/usually does get, but it's certainly a large scale propagation of a BS stereotype. Whatever, I'm actually not that upset. Just more reasons to avoid the general areas of GamingGaf.
