There are many unsavory things some people will do when they can get away with it. Instead of just "getting over it", we fight it, and make laws.
Brigandry was once a noble profession, but is no longer. In fact, killing random travelers on the road and robbing their stuff is dealt with most harshly nowadays.
Slavery was once the natural order of things, and many people no doubt "just got over it", but not all. And now it's illegal.
Pinching bottoms and feeling women up in the workplace or on trains was once part of a perfectly normal day, and the argument at the time was "What? We're not raping them or beating them! They're not getting pregnant or anything! No harm done!". And many women no doubt sucked it up and "just got over it" because it's "just the natural state of things". But not all. And now it's illegal.
Just because abuse is rampant doesn't mean you're obligated to tolerate it. You can choose to fight it, and should you succeed, others who would not or could not, will thank you for it.
