This kind of statement is something I avoid like acid... I mean... I hardly think men are smarter, don't get me wrong...
But I do believe that women and men are too different to actually compare. We each of a very different way of thinking, and each gender has it's strengths and follies...
I don't like "Black and White" statements.... I love gray, the whole world is beautifully gray in all shades and hues
As for not wanting kids... I don't really understand why people are so occupied with judging everyone according to their own standards...
I honestly cannot fathom why people should believe that there's ONLY ONE right way to live this life...
To some, not having kids could be the best course, for others, it may not... and both are just as fine.
Prejudice is judging someone due to a trait said person has no control over and that doesn't necessarily hint at their personality...
I think that if your experience proved that you do not get along with a certain type of people, it makes no sense to force yourself into annoying situations only to try and find the exception...
As long as you do not make generalizations that actually affect them in any way(such as not hiring them for instance), it seems like common sense to me...
