From what I could tell these are literally political attacks taking things out of context. I saw one saying that Stallman said it was okay for people to pester for sex. Then I went and read what he said and no where did he say that.

The problem with attacking Stallman on a lie then saying "Yeah, but there was other legitimate stuff too" is that the initial misrepresentation demonstrates bad faith - which casts doubt on later insinuations.

If there is stuff that Stallman legitimately has to answer for, so be it, but in the context of kicking him while down, Gish-gallop style, this is pure justification after the fact.
