I think there's a big split - all things academic, this is probably the best site out there.
Moral/religious debates however, in my opinion, have been a disaster. Whilst there is the overwhelmingly respectful majority, there's an amazing disrespectful minority that I've been unfortunate enough to be on the receiving side of. I think EVERYBODY needs to understand that name calling, intimidation and insults are never acceptable. Literally everytime I have seen something that I think is personally hurtful, I have PM'd the mod who I thought was most appropriate - only once have I received a proper, helpful and mature response.
It is intimidating, to disagree with people who are both influential and highly vocal (in often overly aggressive ways). I'm lucky enough to have the self conviction to publicly disagree with what I don't believe in, irrespective of who else voices their opinion. Other people, equally as valuable people, are not so lucky. Losing these people's opinions not only diminishes intelligent discussion, but alienates members or what is meant to be a mutually beneficial forum.
Atarnotes is a genuinely wonderful place - I just wish we could keep our statements objective and polite.
