I wish the conversations here could be more respectful and moderated.
However, on these boards, it seems that anytime a mod tries to clean up a thread or tell people to cut it out, all kinds of GCers go on screaming about freedom of speech (which is b.s. I'm pretty sure GC gets no federal money

)
There's also fewer mods on these boards, and ones that aren't around quite as much. Also seems that it's a more passive moderation- cleaning up posts, etc. instead of a more active moderation.
Also, perhaps there's more respectful conversations in the NPHC forums b/c you're all brothers and/or sisters. Here, it's just a hodgepodge, and there's even a lot of non-greeks here. So that respect for your sisters/brothers isn't really present. The NPHC groups as a whole (in addition to individually) have a very strong community and respect for each other- and appear to me also as smaller groups part of a bigger brotherhood/sisterhood (NPHC).
As for respect between NPHC forum users and the GL/ChitChat, etc. users, there has been lack of respect on both ends at different times. I can think of a couple recent examples, actually, where there was disrespect on both sides.
