Someone will always give shit. It's what people do. I've said since my early 20s I didn't want children, and lots of people throughout the years said there was time to change my mind, or I was selfish, or bla bla bla. It was so nice for that shit to stop in my 40s. Folks don't like it when someone else does something with their own damn life that they don't agree with, they want everyone else to own and embody their opinions and beliefs, it's the way of the world. I myself used to be quite pro-life, and there are several words I now wish I could take back and replace with compassionate responses. Perhaps one day those who negated you and your choices will recognize their ignorance and regret how they spoke to you. As
@waterbottleman said, that's not feminism. Feminism at its most fundamental is about a woman's right to choose. What those folks were spouting is, I believe, called shittyism in both medicine and the higher academic circles of philosophy. It's a viral epidemic that masquerades as belief systems and is no respecter of gender, class, or status with regard to who it infects and expresses itself through. I'm pretty sure anthropologists have uncovered expressions of shittyism in ancient cave paintings and Egyptian hieroglyphs, but as with ctb methods, please do the research for yourself and don't just take my word for it.
That said, I acknowledge and have compassion for all your disappointment and suffering.
