To hopefully put this to a rest:
It has been stated several times, all over the forums, that "Freedom of Speech" applies, so long as it doesn't break any of Aeria's rules. You are free to speak as you choose, however you cannot do so in a way that violate any of Aeria's policies. Once you do, you come into danger of losing your privilege of membership.
As for the topic on hand, I give you a quote:
2. There will be no discussion based on a national, political, religious, sexual or ethnic nature.
Also, as TenRing suggested, it's safest to remain away from such topics in public settings. Such as, the forums, public game chats, etc. Mostly because they can offend others from other countries that come to Aeria to take benefit from the services that the company offers. Just because you believe in something, doesn't mean they believe the same thing. Think about it retroactively, as well.
I think the best thing that could happen to this topic would be an immediate lock. It's gone from QQ in a direction that could turn out hazardous.
