Unfortunately, the choices available when filling out that portion of the profile leave a little room for confusion. If someone marks "100% straight", that means the person is 100% straight.
Yeah, except you keep saying that "straight" means "100% straight".
If they mark 90% or 80% or 70% or 60% straight, that means that they are bisexual
So someone that puts 99% straight, 1% gay would have to say, "hi, I'm bisexual" to stay in your good graces?
That's insane. Most straight people are not 100% straight--in fact, it has been demonstrated numerous times in study after study that there truly are very few people who are honestly and truthfully 100% straight.
But by your definition, straight men do have sex with men, therefore, by your definition, all men are straight.
Nice try, but no. Do you even read before you post? Straight men generally have sex with women ("clearly predominant preference for the opposite sex" should ring a bell). That's all there is to it. Your definition excludes anyone who has had an erotic dream about the same sex, anyone who has experimented in college, and anyone who might have had 47 female partners and one male relationship.
Yeah, experts in human sexuality, like Suzanne Frayser, William Yarber, Robin Sawyer, Spencer Rathus, Jeffrey Weeks, Gayle Rubin, and Carole Vance, to name a few. I never quoted Wikipedia, incidentally, but I wouldn't expect you to know that, since you're walled up in your haze of refusing to comprehend.
Seriously, pick up any text and quote for me the section where it describes straight people as 100% heterosexual, and bisexual as anyone in the 1-99% range. You can't, because it's a ludicrous idea not supported by research, fact, or normal usage. The broadest commonly accepted range is the IQR.
You can then explain to me how the 85-90% of the population that is considered "straight" all falls into the very end of the scale, despite biology and logic. You might then justify how you see a continuum with hard edges where 99% of the scale is "bisexual" when in fact this is the smallest of the three groups. Then you can explain what good a scale is where 95% or more of the people fall into a single point, rather than spread evenly around it, as occurs whenever an actual study is performed.
Maybe when you work your way through that exercise, you'll realize that where the line between heterosexual and bisexual is drawn isn't at 99.99999999%, and in fact there is no line. For one person, it might be 79%, for someone else it might be 85%, for a third person it might be 75%. It is unrealistic and dishonest to expect that straight people achieve your required level of 100% purity--I'd be willing to wager that almost no one in the history of the world truly fits that bill.
And you know less about my credentials than you do about sexuality.
Not really, no. If you think someone who is 90% straight can't call himself straight, you're clearly not someone who has conducted studies or research into human behavior and sexuality. You might also know that by your continual resistance to cite any text supporting your ideas (because there are none), and the fact that you took a crack at the Wikipedia article without following the links it contains to legitimate and respected sites, studies, and bodies of research and instead used it to deflect from the actual statement of human sexuality experts (not Wikipedia authors) disagreeing with you.
Just face it. You've provided zero factual support and constructed a world for yourself that doesn't even remotely resemble the real one.
