Today at work on of my work colleagues was relating a story where she received some strange feedback regarding her children. The first thing that popped into my head, so I asked it, was "is she a parent?". The answer was no.

Anyway, before I finished my question, another work colleague (who does not have children) got all offended and said we could not blame it on that. I argued, yes I can, as I have been there and said some pretty daft things before I had children.

So is it right or wrong to blame strange opinions/statements on not being a parent? Does it depend on who it is? What the opinion is? How it is expressed?
