So if a woman on her own was walking down a lane at night on her own and a man is approaching her staring at her breasts, do you admit she may feel threatened?
Now imagine it's the same alley in the daytime, but no one is around. Potentially alarming?
Imagine it's daytime in an open street but she has previously been a victim of sexual assault. Terrifying?
No one knows what stories people have. It's common bloody decency to not openly gawp and leer because you have no idea how that person feels about it.
You seem to be defending the right of a man to make a woman feel self conscious, embarrassed, threatened or all of the above because he happens to find her attractive?
