Sexual assaults are a single part of the equation. Men should feel intimidated also. Did you know that statistically adult males are assaulted, either by other male or be females almost as frequently as females are assaulted?
There are a lot of other ways which cause intimidation. If I stand upright, without slouching, I intimidate the majority of people I pass; and it's fully unintentional! Then, there are the monsters out there, those without any moral compass, and lacking critical empathetic emotions, and sometimes guilt. The less intelligence and abused themselves tending towards violent outlets.
I didn't bother to read most of the thread. Random people's fears have little bearing on me, but, I wanted to point out that men are the victims of violent crimes more frequently, domestic violence is very close to even, Singling out the females for such a broad question is a bit biased.
No hate, just a (Probably duplicate) question about expounding on your ideas.
