It can not be your business and you're allowed to still have opinions on it. It's one thing to discredit opinions you think aren't someone's business - that's fine, maybe even understandable.

But everyone is entitled to their opinion, and you can't just make people shut up. It doesn't work like that.

If you feed your kid rocks yes I think you are stupid and yes I think you should've worn a condom. Whatever, who cares, listen or don't.
