Told my extended family that I didn’t want kids.

I attended a Sunday dinner at my grandparents house with my extended family and parents. My aunt Emily began to rant about how difficult her kids have been for the past couple of weeks. I commented that “This is why I don’t want kids”.
My family turned and looked appalled due to my comment. They all began to pitch in passive aggressive comments. My other aunt Nikki said that “I had to have kids to know the pain I put my parents through” and my father pitched and added that “I had to pass down those genes”.
This kind of behavior towards me just pushes me further to not want to have kids. I’m so sick of the belittlement and being treated like an idiot. I get comments all the time that “I’ll want kids when I’m older” or that “I’m too young to know if I want kids”. These comments are pushing me over the edge and I think I might lose my god dmn mind.
I wish that people would respect my life choices and realize that I don’t have to live their life.
Edit:
Thank you all for your replies. I’ve set up my vasectomy appointment for October and none of my family knows lmaooo.
