Number, no offense, but I'm concerned that you're a bit insane. Young boys, irrespective of race, have it very tough, but for the exact opposite reasons you seem to think. Everything in a grade school classroom is "girl friendly". "Sweet" pictures of little bunnies everywhere, art projects where you have to make little hearts, blah blah blah. In many schools, recess has been made "illegal", and in those where it is not, it's illegal for the little boys to play a sport because "they might get dirty". My mother was a public school teacher for many years (as was her mother), and they were both sickened by it. She eventually quit when the boys were no longer allowed to play games like soccer or touch football. Talk about major disciplinary problems when little boys are bottled up all day. When I went through school years ago, it wasn't so bad, but we were still quite disgusted by the "sissy" decorations in the classrooms, and the way everything was oriented toward the girls (i.e., forced to watch Barney movies which we were WAY too tough for, lol). We were expected to be little marshmallows and taught that men were supposed to cry every time something happened that didn't please us. Luckily, we all had parents who didn't try to destroy our natures, and grew up just fine.
I would love to know what the hell a "gender straightjacket" is? You see, there's no ambiguity about gender. You're born with either male or female genitals (unless something goes wrong, which is a rare but serious medical problem). After that moment of birth, you've been "assigned" your gender by nature, and it can NEVER change. Even surgery doesn't really change it. It only changes appearances. It is 100% natural for young boys to play rough games, get into squabbles and fights and eventually grow up and learn how to be self-sufficient and productive. If you don't try to mold them into a blob of weakness and jello, they will naturally run this course.
Wow... sorry, off topic, but that was weird. To answer the question, I don't think either side could measurably have more adult men living at home with mommy and daddy. Stereotypes would tell us that all "Liberals" are gay, live at home with mommy and daddy, and don't have jobs. Definitely not true, but stereotypes DO come from somewhere. The stereotype of the "Conservative" is that they live in trailer parks next to Sissy and Bubba, drive an 76 Dodge Ram and carry a shotgun around barefooted. Obviously, the majority of folks on both of these imaginary "sides" are not anything like the stereotypes. The other "side" just molds the stereotypes around the low-lives their "enemies" attract.
We Libertarians are also stereotyped. Evidently, I'm a pothead who wants to live in anarchy by some people's accounts, lol. This is funny, since I haven't touched a single drug or drop of alcohol since my "bad" teenage years, and I'm definitely not an anarchist.
