my dad thinks it's "weird" that fertile couples adopt kids

He thinks fertile couples who have a choice to birth kids but would rather adopt are choosing the easy way and "don't really deserve to be parents". Basically he thinks that a woman has to sacrifice her body to be a "real" mother. He says that it's their choice, but that he'll still judge them. Jesus christ. As someone who is scared of pregnancy that really makes me feel like he would see me as less if I ever did adopt (I'd rather not have kids at all, but adoption is my top 2nd option)
