I'm going to select my following words very carefully, because I know they will stick around a while:
Just because somebody feels like a boob after being dissatisfied with the results of a post, doesn't mean it should be deleted. Grow some thicker skin, get used to the internet, and realize that the responses you got weren't even inflammatory. Some threads DO get out of hand, and some are obnoxious. The thread you seem hung up on, was full of several comments from people that were either 1) concerned about their hobby or 2) concerned about your well being. It is still full of advice that can be learned by anybody else that might be interested in a similar topic.
