@celesteh I always thought of RMS as part of the Hippie movement. Not only does he look and behave like a Hippie, this ignorance of especially sexual taboos is part of the Hippie culture. Certainly, RMS is a rather special case of a Hippie.
The Hippie movement was in significant parts a success, but is nowhere secured. The movement as a whole is too big for any single person to cover everything.
Did he care about the part of the movement you care most? Not enough, for sure, as expected.
