I don't consider LW particularly bad - it seems considerably saner than a typical internet forum of similar size.

I have a similar impression.

LW was the first internet forum that I had serious exposure to. I initially thought that I had stumbled onto a very bizarre cult. I complained about this to various friends and they said "no, no, the whole internet is like this!" After hearing this from enough people and perusing the internet some more I realized that they were right. Further contemplation and experience made me realize that it wasn't only people on the internet who exhibit high levels of group think & strong ideological agendas; rather this is very common among humans in general! Real life interactions mask over the effects of group think & ideological agendas. I was then amazed at how oblivious I had been up until I learned about these things. All of this has been a cathartic and life-changing.

Is my impression right that most of drama we get centers about obscure FAI stuff?

Not sure, I don't really pay enough attention. As a rule, I avoid drama in general on account of lack of interest in the arguments being made on either side. The things that I've noticed most are those connected with gender wars and with Roko's post being banned. Then of course there were my own controversial posts back in August.

I've seen some drama about gender and politics, but honestly a lot less that these subject normally attract on other similar places.

Sounds about right.
