I don't want to immediately be labeled as an asshole
What makes you think you will be labeled as an asshole right now?
Because the name of my university program accepts assholes and I don't want to be part of that. I am not an asshole.
Overall, don't worry about the bullies who call others names. Its all about them and not you. They feel like they lack something.
But others think it's okay to label people according to the program they choose.
While some people do like to generalize about others and think that all people are some way and that it is okay to call them names, it is not okay. If you don't want to be called an asshole, you can tell people so that they don't. If they don't listen then it is on them.
