There are other forms of liberal/leftist bigotry such as much of third wave feminism, generalized anti-religious sentiment, and generalized attacks against businesses and their members, not to mention the frequent view that anyone who "should" support their cause for demographic reasons but doesn't is a mindless, brainwashed, uneducated, self-hating traitor.
I've also found that a lot of "enlightened" and "educated" liberals tend to be more supportive of eugenics than on average.
OK, even if I'd actually buy everything else this is absolute bullsh*t.
It may not be as frequent on this forum, but the amount of overgeneralized vitriol against CEOs and other higher-ups of businesses from many on the left is quite a real thing. Some deserve it, of course, but that can be said of every group; however, the left has a tendency to demonize them as a class of people who they can scapegoat all sorts of issues on.
