I hear this and I agree. It's obviously a serious problem.
As a side issue. There's also a different, deeper problem. Any Q&A site that's actively hostile to people who ask questions is going to become toxic and intolerable within a few years. I'm pretty sure that's true even if the hostility is reasonable and justified.
As a newsgroup user since 1986: The problem with the original Eternal September was not only a tidal wave of ignorant new users. It was also that a large fraction of the experienced user base were smug lunatics long before September finally arrived.
Sorry for the like "radical candor" here.
