How about just not discriminating?
Do you mean, "Let us be willfully blind and refuse to engage our senses, not recognizing any differences between homosexuals and heterosexuals despite large behavioral differences (beyond sexual preference) which do exist."
Or do you mean, "Despite your arguments, I categorically state that no differences between these groups exist (beyond the sexual preference of each). I state this without any argument of my own, please accept it for no reason that I care to state."
Nonetheless, it's a tenet of polite, modern society that slight demographic variations are not turned into generalizations over entire demographic groups.
Not allowing gay people to adopt because they're "more likely" to commit abuses is discrimination, whether or not you have the data to prove the logical statement.
I think that sufficiently sharpens the contradictions.
But just to make it crystal clear: you're not being down voted just because people are too polite to confront the truth. You're being down voted because you're not very smart.
Dude, you essentially made up or misinterpreted the numbers you're using[1], then you make what amounts to completely irrational sweeping generalizations based on nothing but two numbers and/or your (limited) social experience.. And, admit it, you know these conclusions are offensive. Not only that, but you can't even stand by your intentionally ambiguous statements about homosexual behavior after you post them -- you're not only an asshole, but completely gutless.
i.e. Shut the fuck up, kid. You have no idea what you're talking about.
Try the average husband. When the wife asks "does my butt look big in this", there's an immediate and well acknowledged convention to be polite rather than logical ;-)
Howver, a corollary of this tenet of modern society is that unequal representation in a given field/endeavor is prima facie evidence of discrimination, regardless of differences in group median ability. I trust I do not need to provide examples of this?
You're basing your judgments on the flamboyant feminine gay men, the ones who you know are definitely gay. That's a very biased sampling to base your judgments on.
