Why are my parents forcing me to socialise?

So basically u mom told me u RLLY need to socialize with the girls in ur class. I told her I don't want to cuz I don't give a d*&^ abt their convo's cuz they aren't goody two shoes like me not even in their heart let alone in their heads ( which heart is a minimum for me). I am NOT being ungrateful am I?
Like ethically speaking, god has given me a class full of ppl, I don't talk to anyone there rlly except one girl. I was just wondering.

I have this other friend group I enjoy, a bestie from that group that had to move schools, two friends from other schools, a childhood bestie. Tl;dr I will be here forever if I were to do TWO thingss
One, list any possible ppl I can talk to ( even one-off) so that I don't feel lonely.
Two, any and all compliments I have received in my life even when u DON'T factor in family and teachers.

Btw, I have online friends. Do you think telling them that would help or hurt my case ( in other aspects as well)?

Idk how I can convince them I just have my needs met and my plate full and I am DEAD uninterested and why in the WORLD do u think I am going to regret my decision.
Thank you!!
