/Girls should not be allowed to play alone with boys./
When I was little, I used to play with the boy-next-door all the time. And guess what, we never dated and he never knocked me up. Nothing bad happened. FAIL.
/The parents should see to it that she plays with other girls./
Why can't she play with boys AND girls? Some girls prefer being with other girls; some girls prefer being with boys, and vice versa for boys. The same holds true when they grow up. People are individuals. You can't just push them all into one box.
/This is important for many reasons./
Do tell. *sarcasm*
/She should play only with toys that are uniquely for girls. This, by all means, should include dolls, doll clothes, housecleaning equipment, dishes, pots and pans, etc./
Yep, everything you need to become the perfect fundie housewife! I never played with pots, pans, or housecleaning equipment (who the heck plays with housecleaning equipment?) and the only kitchen toy I had was an Easy Bake Oven which I never used because it was broken. I did play with Barbie dolls, but I also played video games (and still do, with my brother and dad, no less), card games (Pokemon, Yu-Gi-Oh, you name it), and with action figures, too. Some girls don't like "girly" toys. And some boys like playing with dolls (and I'm not just talking about action figures). And what about the boys who want to become chefs when they grow up, who do want to know how to cook? They shouldn't be allowed to play with pots and pans, because they're "girly?" Give me a break.
/She should participate in sports enough to become coordinated but she should not excel in sports./
Because heaven forbid she actually rise above the superior men. You know, a lot of people held this kind of view during the Renaissance: teach a woman how to read and write, but don't actually allow her to express herself or earn a profession that way or dare to surpass the godly men in poetry or languages. Just let her do all of that so that she can impress your guests the next time you have a house party. So, yes, humor the little woman by letting her dally in sports, but don't actually, you know, let it become anything more than that. Patronizing jerk.
Guess what, Hyles, I play basketball and baseball with my brother and dad, too, and more often than not, I would beat them. FAIL.
/If later she marries a man who is very athletic, she could become more proficient in some particular sport that he enjoys,/
Oh, that is a riot. Oh, yes, one that HE enjoys! Never mind one that SHE wants, if it's not coordinated to her MAN's desires, then it's absolutely useless! If he plays football, she MUST play football, if he plays basketball, she MUST play basketball! She can't actually differ from him and play a different sport that he doesn't play, you see, because that would make it seem as if her life didn't entirely revolve around him. *snorts*
/but if she becomes an expert in a sport that is usually associated with men and boys,/
And which one is that, pray tell? Every single sport that's out there has men competing in it. Even ice-skating and ballet (even though it's not really considered a sport) have men.
/it could prove embarrassing to her future husband,/
Because heaven forbid his wife actually be better at something than he is. Who does she think she is, rising above her station to surpass her godly husband? You know, whenever I beat my dad and brother at video games or basketball, they are NEVER embarrassed. Granted, I don't win every single time, but they are never embarrassed that - gasp! - a WOMAN beat them. I don't get embarrassed whenever they win, so why should they? If this hypothetical woman's husband gets embarrassed, then it's HIS problem, not hers. It's HIS problem that he's such an insecure, whiny, self-centered crybaby that he can't stomach the thought of a woman being good at something and posing a threat to his superiority complex.
/and for that matter, it could entice her to become more masculine than she ought to be./
I've already told you that I play basketball, video games, and baseball. I also can play tennis and golf, as well. And guess what, I'm not a tomboy. I'm not super-feminine, but I'm not masculine, either. Get a grip.
