I'm not going to try and argue against you beause there are few things in life I find more hilarious than hypocrites and fanatics but I will defend TvTropes (in part)
It is not a bad tool for writers. I'm a writer and I've used many of the tropes found within only after finding them on the site. True it doesn't document why a trope is used, but if you're an intelligent person in possession of a real live brain then you should be able to figure it out. What he should perhaps be saying is that TvTropes is a bad tool for bad writers, but of use to good writers. Beyond that, if you hate the forums so much, why not just stay away from them?
As for taking personal exception to individuals, I'm sure if you went through any site, even this one, you'd find people with absolutely reprehensible views, buried in amongst the thousands of other users. To characterise an entire user base as being comprised of only one group of people based on a sample of less than twenty is at most ridiculous generalisation and at worst a deliberate smear campaign. And Something Awful are the absolute last people who should be ragging on TvTropes for having bad personalities on their forums.
Of course the recent moderation attack was a little over the top. Argue all you want about other forms of lolicon and whether it's a valid art form or not but Lolita is listed as one of the top 100 greatest novels ever written by The Times, so you'd think maybe it crosses the line into being 'art.'
