Why do parents turn a blind eye when their kid is a bully or an "ass"

I have an eighth grade class that I inherited mid year, from a teacher who left the profession. They are chaotic and have no concept of personal space. Kids have been removed from the classroom for kneading in another kids hair, kids walking around slapping other kids on the but, and many other things. <br><br>Today, one of the kids in the class walked up behind a girl and pushed her head onto her desk. She ended up with a black eye. The girl went to administration and she told them she didn't want to press charges, she just wanted to go home. She went home with her mother and the principal texted the boy's mother. The mother said the girl was lying and that her son was an angel and would never do that. She said that if her son did do that, it must have been in self defense and that the girl was probably "a bitch". <br><br>I had a similar situation in which I had removed a student for walking up behind another student and pulling down his pants. The mom said that she had never heard one negative thing about this boy, and that he is an "angel". Because teachers are " Basics, and don't know what to do with my kids advanced spirit". I've heard every excuse and it makes be angry. Parents can't accept their kids being assholes, they love to pretend that it's not their problem. I've literally had parents try to fight me for detaining their kids for starting fights, and I've been told I'm a stereotype of an "asshole teacher" for not wanting their kids to walk around and disrupt my class. What is wrong with parents today? Or is this how it's always been and I'm new here?
