Um, ok. Not sure what you mean, but whatever. I don't talk smack on here on a regular basis. Actually, I don't think I do at all, but I digress.
I'm ok with anything on the site because nothing on the internet can get me upset enough to leave a softball site. I've had my run ins with Country and Joker, who hasn't? But WGAF? I went back and forth to kill time. I really don't care enough to get upset. It's a softball site. I don't even get mad on the field, why would I get mad online? But, like you said, that's just me.
People are sometimes unwilling to accept responsibility for asking an idiotic question. If you ask a stupid question you should expect some level of backlash in a public forum. Instead of leaving the forum because a few people like to call you a dumbass for asking which bat is the best for hitting line drives, think about what you asked and maybe try to do better. Don't leave because they hurt your feelings. That's what I mean by Participation Trophy mentality.
Your point might have more merit if more than a few people verbally abused stupid questions. I think more people say ignore the aholes than the number of aholes doing the abusing.
If you're in a public forum, can you expect everyone to play nice 24/7? And, like you said, everyone has a different line of demarcation for what they deem unacceptable. But, I really don't think that Joker, Country, et al, are the main or even a major reason this site has changed. It's a complex answer to that question.
