The primate example is weak, because they aren't rational thinkers the way humans are. They aren't as in control of their emotions, or aware of things beyond their base urges. They screw each other because it feels good, or to establish dominance. It's also found in mental hospitals where some retarded people end up unfortunately. They screw anything and everything, just because it's pleasure for them.
That's debatable, but if I were to concede the point that these primates are less capable of rationalizing their behavior, would this not
support my argument? If they are less influenced by social factors, clearly other factors must be more influential. Without any of that pesky reasoning getting in the way, animals and even people (or so you claim, I haven't really read anything about sexual behavior of "retarded" people) resort to bisexuality.
Now when you think of rational humans of normal intelligence, it's saying that they are lumped in there with apes and retarded people. I can't help myself at all. But in the same breath, they want to be considered completely normal and attack anyone who says they are seeking therapy to become straight.
Not sure what you're trying to say here or how it relates to what I've said...
We seek help for dyslexics? Folks who see letters jumbled up. But it's not P.C. to say the same thing with gays? Heck, psychotherapists are debating about whether to put Gender Identification Disorder (our beloved trannies) BACK in the DSM.
I don't care much for being politically correct. If gay people are happy being gay, good for them. What does it matter what the medical term for it is? Hell, being left handed is an abnormality, but I don't see any point in trying to "fix" it. I don't make an effort to inform left handed people that they are abnormal, but I will tell them that if I'm asked. Whether this abnormality is positive, negative or neither is another matter.
In the end, bisexuality as default for social animals doesn't make sense, because over time, bisexual and gay animals would be selected out in favor of straight animals, who would be spending 100% of their mating time in relations that could actually produce offspring.
It makes perfect sense. You're just thinking on an individual scale, when you should be examining the community as a whole. As I've said, it is well established that sex reduces aggression within a community. A community that is less aggressive towards each other are more likely to succeed than a community that is more aggressive. Thus, the genes shared in the former are more likely to spread to future generations.
The exact bisexuality ratio is rather arbitrary of course, but let's say 80/20 just to illustrate the point, meaning, roughly speaking, being willing to have sex with your own gender, but choosing a partner to mate with of the opposite gender. As long as you are able to reproduce with at least one female, it doesn't really matter how many males you screw around with on the side.
