Whoa, that is pretty nuts! I've been on Wikipedia for ~10 years, and for a few years (mid-2000s) was on the arbitration committee, and never ran across anything like that, either first- or second-hand, not even for the brief period of time I was somewhat active in editing articles relating to the Israel-Palestine and Greece-Macedonia disputes. The worst I've gotten is angry emails, though even those are rare and it mostly sticks to angry talk-page messages. Perhaps I was lucky; or perhaps "race and intelligence" as a topic brings out an exceptionally insane crowd? Sounds rather unpleasant. I mostly edit articles relating to archaeology and (pre-20th-c) history these days, and I don't really run into trouble. If anything, my main complaint is not enough other people around; parts of the encyclopedia feel like ghost towns, where you can write whatever and nobody will comment either way.
