It is extremely prevalent.
It needs addressing at root cause - male behaviour.
Even stuff where technically they aren't doing anything wrong e.g. slowly running eyes up and down you, when you're 14 or whatever this is really disconcerting and all adds up to this discomfort in general in public spaces as it happpens so much.
Men say "oh we can't help it we don't realise we're doing it are you saying we can't look at a femlae ever???????" which is disingenous. I am sure they manage not to look at their daughters / mums / sisters like that. And as adult humans are capable of self control. Do they do it to their female colleagues / bosses at work? Like fuck they do. Of course they can control all this behaviour.
And why do so many of them take NO interest in or concern for the effect on tehe girl on the receiving end? I mean som enjoy the reaction. But many just ogle and move on. They don't really see us as people at all. Is the answer. Sex objects / ornamentation for their visual pleasure. This is where "smile love" comes from & why so many react badly if they are pulled up on it >> ornamnets aren't supposed to object to being viewed, are they.
