Harassement and abusive behaviours are a way bigger problem that people think it is. My opinion is that more than 50% of people at least are harassers and abusers to a degree or another. This is just how society used to work not long ago and since the dawn of mankind.
What can be done is teaching kids what harassment and abusive behaviours are. Most people think their behaviours are normal. My mom who has a relatively high education speaks to me in a completely abusive way. As do my father who has 2 engineering degrees.
