I'm so tired of being judged for being Childfree

I am a young woman (20), and in my culture, we have a tendency to rush into marriage and children. So whenever people from my family and friends ask me about marriage and kids, I tell them I don't plan on having any. I get a lot of weird looks, and I have been judged and lectured about how important children are in shaping the future of society, etc. Just to be clear, I am not afraid of commitment, I just don't want to have kids. I'm a bit of a control freak, and I always want to have control over how I spend my time. I am giving serious thought to having a tubal ligation. I just want to know how I can respond to people who are against my choice. Also, I am not trying to offend anyone, but if someone is childfree by choice, I have nothing but respect for them.<br><br>Tldr: I'm tired of being judged for being childfree, and I want to know how to handle people who disagree with my decision.
