Stallman has said some very stupid things when it comes to child abuse. I don't believe he is a sexual predator but a old odd looking guy making those sorts of comments will put people on guard.
Sorry that the new, rich pseudo-left with their stock options and identity politics no longer approves of that look.
So much for diversity.
Simply putting on a clean shirt, some proper shoes and having a shave does wonders in this regard.
That is the reality of it unfortunately.
EDITED for clarity.
Just curious: what do you think of the view that such superficial acts are gestures of respect towards one's fellow man?
I'm sure that the things you mention never had 100% approval of the left in the 1970s. In fact I've never met a leftist from that era who held those views, and I'd be quite disturbed if they did.
