Yes its harmless enough fun
But it isn’t.
My wife gave up running in our local park because she got fed up and intimidated by men making comments about her breasts.
My daughter got fed up and intimidated by men making suggestions to her as she walked home from college.
This kind of small scale, low level grinding sexism and misogyny is one end of a spectrum that sees women considered as less than people, as objects and so on.
Like I said, ask your wives, ask your mums, ask your daughters what kind of effect this has on them.
Then ask yourself what it must be like to be a 14 year old girl in the back of a taxi, late at night, being taken to see the drivers ‘friends’.
It’s easy to pass it off as a bit of fun, it’s easy to say it’s harmless, it’s easy to be a small innocuous part of the problem rather than be a part of the solution.
