Fundamentally, the perpetrators of the most egregious offenses do not believe and are very quick to dismiss the idea that they are actually doing anything wrong.
This is a battle that women are still mostly fighting alone because how we feel and how we are treated is important to us personally. People who don’t care about our feelings don’t care that they hurt us. What’s worse is that every single one of the offenders you describe got a positive charge out of what they did to you. It was fun for them. Progress is so slow on this issue because so many of the perpetrators truly believe that they are just having “harmless fun”.
