From the point of view of a women, it seems like all men are harrasers, gropers, cat callers.
But really, this is just a minority of men, who aren’t afraid to approach lots of women.
The majority of men are waiting around hesitant to approach anyone, scared of embarrassing themselves, being rejected etc. These men rarely approach women, so women don’t factor them into the equation.
People like to hyper-focus on the small minority of morons and generalize across all men. Which isn’t a particularly balanced or level-headed way of looking at the issue.
Also, for men to learn to approach women, as you say, they need to practice. That means that, for the less socially calibrated, they need to spend a period of time making mistakes, being werid, being accidentally creepy and at times being too forward. Untill they learn to calibrate themselves.
Women often want men to be smooth and calibrated from day one, which simply isn’t the case for a lot of men.
