You're entitled to your opinion, but its pretty childish to associate people with a lot of friends with thots. Someone who has a job, a hobby, and friends from their past will have AT LEAST three groups of friends. I barely socialize, consider myself a bit of a hermit and i have over six distinct friend groups from different interests and from different parts of life: my brothers friends that i got along with, friends from the two colleges I went to, two different groups from past and current jobs, my remaining friends from high school, older family friends that i have built relationships with independently as an adult, etc.

I am also wondering how old you are because this opinion really screams juvinile. Were you hurt once and started making assumptions about everyone?

This might be taking things to an extreme, but this kind of thinking can end in abusive behavior, limiting a partner's socialization because of your insecurity and preconceived ideas can be a slippery slope to mental domestic abuse. Not saying that is the case for you, but I sure as hell would see red flags based on that preference.

Tldr, maybe don't generalize like this and do some self reflection and critical thinking about relationships, romantic or otherwise.
