In all seriousness, I don't see a lot of that on this board. Maybe I'm blithely ignorant and naive (I'd like to think not, but of course, that's the curse of naivetee), but I don't see a lot of belittling and defamation... outside of the political discussions, that is.
In my experience here, most times when someone is offended, it's as a result of a misunderstanding. Usually, it's when someone interprets a general statement as a personal attack, or in some other way projects their own situation onto a critical post.
I see the same thing on KenpoTalk where I have much more experience (most problems coming from misunderstandings, not attacks).
I will say though, I love my time on the forums where I can learn, discuss techniques, ideas, or help others out, encourage, hear great stories, etc. Sure, there's some nice stuff about pointing out the bad stuff, but I have yet to meet anyone that was perfect. Well, except that brunette in college . . . but I never talked to her, so I think that's why she was so perfect . . .
I signed up for Bullshido at one point cause I liked the idea of making sure that people were working hard and not being frauds. I read around for a bit, made I think four posts and left. Way too much ego, bashing, witch hunting, personal attacks, etc. for me.
In real life - my door is open. Come train, have some fun, and if you learn something, stick around. If not, thanks for the time and I hope you find whatever it is you are looking for.
On these forums - don't take it too seriously. Come in, waste some time on the Internet, hopefully learn something or help someone else learn something, and have fun. If that doesn't work, you don't have to read what is written.
And heck, this whole life thing . . . no one survives anyway . . .
