We can mostly defend against men that give out creepy social cues. Guys that are not creepy are far harder to defend against or get justice against: a guy that knows how to present himself understands social signals (almost self defining) and they can often get away with a lot because of that.

Plenty of guys hit on young women (I saw a study that showed that men of any age say they want a 21 year old). Are we surprised to find out "teen" is a major keyword on porn sites? Many men with a social standing (or money) use that to their sexual advantage. Go to the pub and listen to some drunk bro's: there is a large number what a lot of men say is extremely disturbing. I think they are highly immoral; but the attitudes are common and we usually avoid the moral argument and simplify it with a legal argument (statutory rape laws which rightly protect our weak and vulnerable).

I don't doubt that RMS has been an arsehole, and his workplace, voluntary workplaces, friends, family and acquaintances should definitely make him accountable, and take action against arseholery.

However, what seems to be happening here is that Richard is getting publicly shamed and publicly tried and judged guilty for being creepy - no accountability required.
