Maybe those parents have actual morals instead of your weird libertarian attitude to everything?
I'm sorry, but I don't see how people having six is worth getting offended by. I don't have to mention reproduction, that's obvious enough. but six is also healthy, fun and in general absolutely nothing to be ashamed of or appaled by. Sure, if I caught my future kid watching animal porm or child pormography, I'd be extremely upset. But if s/he was watching regular porm, I wouldn't have a problem with that in the slightest. I'm not enough of a hypocrite to judge someone for something I've done myself.
Swearing isn't ven worth getting into, you can swear as much as you want around me, I don't care at all.
EDIT: Yeah, my parents still ask where I'm going if I leave, but if I'm going out to get wasted, I tell them that, and their response is "Call if you need somone to pick you up". No hassle at all, I'm almost 20 now, so about 2 years over the legal drinking age, so they have no reason to hassle me if I choose to go out drinking, as long as I don't wake everyone when I get home it's all good.
