I don't think rainbow8 posts political rants in every manhua thread out there. He's just one of many, many people who seem to have an obsession with China and jump at chances to bring up their political ideas in a thread. "Oh, this GL manhua reminds me of the evils of communism, let me explain, blah blah blah." And if they are told that what they are doing is WRONG, as they're polluting a thread about yuri romance with political prattle, they reply with:
Engaging in a discussion about history and giving facts is hardly "babbling".
Or other such garbage which ignores the issue, to wit: no one cares about the nature of your rant, only that you're ranting in the wrong place! Go to a political forum to debate whether your tirades are factual or stinking propaganda!
This is a problem that keeps growing. In the MDL thread, not too far ago, some guys compared the PRC with Hitler's Reich and started posting pics of nazi camps and Jewish victims. I can't recall if rainbow8 took part or not (all the messages were deleted). When OrangePekoe told these guys to stop they were indignant and talked about negationism! In the end people were banned and the thread was thoroughly purged. I wonder if perhaps a rule should be made to specifically bar anticommunist speech from manhua comment threads? Just to make moderating and moderation calls easier.
