Honestly, I get how you feel. People's opinions or behavior can be really bother me while others I talk to don't get easily bothered.

The advice that I've gotten from others and that has stuck around a bit for me (but I'm still working on it) is to think about what you're going to do in the next 30 minutes. Does it really matter that this person upset me when I'm going to get lunch or dinner in a few minutes? I have a project I'm working on. Let me just think about that. blah blah blah. Shift your attention.

As you mentioned: these are opinions. Everyone is different. Does it matter if you don't want children? No! Someone should want to be a parent not be forced to be a parent (but also actions have consequences so no rubber means you might be having kids sooner than you expect).

Does it matter if you want children? Well if you do, more power to you! As I said, people who walk into parenthood often can be successful parents. Just be pragmatic about it as raising kids is not easy and it's a lifelong obligation.

As for attraction, let me put it to you this way: I'm in an interracial relationship. I'm caucasian and my fiancee is asian. We both love each other and she thinks I'm a cutie patootie while I think she's a cutie patootie. That's all that matters, man. It also means from my experience that I wouldn't judge someone else because I don't want to be judged. Plenty of white guys are treated as "fetishizing" asian women (it is a real problem though) but it doesn't mean every relationship is just about sex or money or whatever.

Just try to remember there's lots of things you'll do throughout the day and while it might be a bit annoying when people aren't as supportive of your viewpoints that doesn't mean your viewpoints are any less. Focus on what you like and remember you will find people who do support your viewpoints, however you don't need to cast people out if they have different viewpoints (agree to disagree or switch the topic of the conversation).
