All the little girls I know are a total handful and their mums say so too - they're obviously lovely, but way more flighty, emotional, stubborn. Boys are very straightforward, what you see is what you get. Before becoming a parent I thought all these stereotypes were bollocks, but in my experience they hold true.
Well, you know what statistics say about adult men and their tendency for aggression.
I'd rather have a "flighty, emotional, stubborn" girl who grows up into a lovely daughter than a son who might be "straightforward" as a child, but then turn out to be a criminal.
If we're being sexist here, let's mention all the facts, yes?
Now, I don't know why OP would prefer a daughter.
But it is by no means sure it is because she'd feel justified to make a girl into a doll to dress up.
I'd want a girl, too. Simply because I think I am better suited to raising a girl than many other parents on whom girl babies are wasted, and who cage them in a pink prison from the first days of their lives.
So, no, not everyone who wants a girl would force gender stereotypes onto the baby.
Quite the opposite, actually.
