Inspired by a post by @Mrs Pen yesterday.

Obviously we're adults here, so it would be easy to say we're just acting like adults, but a lot of topics talked about on these boards are the basis of mommy-wars (EBF vs FF, natural vs medicated childbirth, CIO, co-sleeping, spanking, etc) but by and large even the most controversial of topics are always discussed calmly and respectfully. It's one of the things I love most about this site, it's like no place else on the internet.

For as easy as it would be for drama to start, why do you think it generally stays drama-free? Do you think it's just because the community is relatively small or that HB just attracts tolerant, respectful users? Or something else?
