Am I a bad person for caring about a woman’s past?

I‘ve used the usual analogies

1. ”why does an employer look at your work history“
2. “why do banks check your credit history”

But I’m being told I’m an incel. I don’t hate women. I am not a virgin. I simply prefer the women that I’m seeing to not have an extremely high number of sexual partners.

I don’t understand why so many people get very angry around this topic. I behave the same way I’d like my future wife to behave.
