Why do people especially have an issue with childless cat ladies?

I am on and never wanted to have kids. I am married to my job and hobbies. Yea I love my cat too. I’m not interested in dating or having a family. Why do men like JD Vance and such have an issue with women like me?

What is the psychology behind it? We are minding our business and we are happy and content. We are not harming anyone. If anything we are population control. Haha
