What is with many young women calling many nerdy looking guys creepy when many of them are quiet? Read additional details below?

I am in college and have noticed this for years here and I also noticed it in High School. Most teens and women in their early twenties don't like to have convos with nerdy looking guys or guys that are actually nerds. I am not talking about hipsters, I am talking about guys that actually look like actual nerds or guys that are actually nerds. Most non-nerdy looking teens and women in their early twenties only like having convos with a nerdy looking guy if they want something from him or they have no choice but to something with him. Most get annoyed when these type of guys try to have friendly convos with them. But I don't get it because if these guys are not sociable then these same women call these guys creepy. It seems like these guys get judged either way. Most non nerdy looking women are ok with having friendly convos with these guys once these women get to their mid to late twenties.
