Why Are Ppl Called Selfish For Not Wanting To Date Someone With A Child?

I honestly think it's not selfish. Someone made a decision in having sex and making a baby. Life gives you choices and you make them. If I choose to date single women with no kids, rather than a single mom I'm selfish? I'm young and not looking for a family type relationship maybe one day I'll have that. But it would be nice if I have a child that I had a say in making with my partner. Then it's crazy how many lesbian moms are out here it's hard to find one that isn't a mom. I want a college or working girl who free to hang with me. We can go places and enjoy life together and if a baby comes along ok fine. I'll be damned if a woman tries to throw in my face the my child was here first line. And we all know most mothers like to use it. A woman telling you that her child comes first and you can go anytime, thats kinda hurtful and of course biologically the kid isn't yours. I wish moms would stop being so defensive when Ppl don't date women with kids. It's not a damn pet and she is having high expectations if she is a good mother. I'm 22 with mo kids and I would love to date a female without kids herself.
