It looks to me like Eridu sincerely holds positions that you would be expected to find particularly objectionable or even have trouble believing someone could hold in part due to a huge inferential distance between what the world must look like (including perceptual valences) to the two of you. He's not presenting new ideas. Some People have been taking seriously those ideas for a long time. Is anyone who is a sincere radical feminist that bring their normal (imprecise and [even more]politicky) ways of speaking to less wrong going to be labelled a troll? If so your heuristic is broken because that's a very common way for people to express themselves.

Also trolling almost always means provocation for a negative reaction. provocation for attention is a sad and pitiable state of affairs more commonly associated with the words attention-seeking whereas trolling usually means looking to upset people for the sake of it which is a much more hostile kind of thing.

Thanks -- I was curious to look into the details of that memetic attack.
