What I detest is the sanctimonious, holier-than-thou attitude that, just because you have kids, you a superior or more evolved human being.
I admire that you made the decision to have and raise kids. I understand it takes huge dedication and effort, and it eats most, if not all, of your free time.
What if I choose not to have kids, and I spend the rest of my life "pre-kids"? What has that got to do with my job? Absolutely nothing. And it shouldn't come into it.
Having kids is a choice, and not a path everyone chooses to walk.
