On GaG and in society this shit comes up a lot.
"We're men we can't help it"
"Boys will be boys"
"It's in our nature"
"If you don't wanna be looked at, then dress like a nun even if it's 100 degrees, fuck you commie!"
Okay I made the last one up....but
Even women say this shit. Seriously do a quick google image search of "boys will be boys" or look up this issue on gag and watch people of both genders swear that it's just natural for supposedly grown people to shamelessly give you the up and down just for trying to get to wherever the fuck you're going because, somehow, in spite of being functioning members of society, they can't break away from this behavior from back when fertile women were mounted like a bitch in heat with no warning.
I think it's high time that everybody stops giving excuses for people to make other people uncomfortable. If you're an adult and you can't help yourself from staring at someone because..."wahhhh we used to do this when we were neanderthals we can't help it" Then I'm embarrassed for or ashamed of whomever raised you. Boys will be boys I guess, but if you want to be considered a grown ass man, control yourself. I have ancestors from thousands of years ago who did nasty tactless shit too, but I don't smash the neighbor's cat's head in with a rock just because I'm feeling a bit peckish.
Sorry Mr. and Mrs. Jones, I was hungry and it's just natural.
