I said what you quoted because the OP said she wanted segregation from men and that they all had ulterior motives/to be feared.
Firstly, I sincerely doubt she said "all" men - but it is a fact that some men have ulterior motives, and that some men are to be feared - and we don't know which ones. They don't wear signs. It is also a fact that sex offenders will often look for jobs where they can gain access to victims.
Secondly, why call somebody "paranoid" even if they do have a fear of all men? It may be as a result of sexual assault, or domestic abuse - but even if it's not - no need to belittle women like that. Women do have good reason to fear men. They're bigger, stronger, likely to be in a position of authority, and sadly, a proportion of them will go to great lengths to sexually assault women. And, sadder still, the vast majority that do assault women will not face justice for it.
