Nature has an interesting way of fluking... but perhaps a little story might help you understand why being sexually attracted to one's particular sex is genetic.
Long ago, there was an asexual organism. It, like many others of its species, was replicating its DNA into two 'daughter' cells. However, part of the DNA in one of the 'daughter' cells was fluked, and when it had grown full size: it did not self-replicate like the others, but inserted some of its DNA into another cell of its same species. Thus began the superior process of sexual reproduction.
Men are the human result of this ancient process, born of a small genetic !malfunction!, or as i like to call it: fluke. Two daughters... one born with a penis, who had a primitive form of sex with the one without the fluke, is responsible for the creation of men. That sounds a lot like a lesbian relationship to me... and it's all because of raggedy old jeans.
So Auto... if lesbian sex was the first form of sex... why should it have been taken out of our DNA? There is no reason for it to have been lost in the process of evolution, because it has not been a detriment to animal survival, just like your apendix and your 4 little toes. If the DNA is not a detriment, then it is carried along whenever a creature (who has the DNA) reproduces, as natural selection has not needed to weed it out.
Instead of moaning and groaning about the state of science today (which i personally am absolutly amazed by), perhaps you devote a little time to thinking about what you are saying.
(PS, i may have gotten one of the particulars wrong with my story above... but since i'm not a super-scientist with a PHD: i don't have to be right all the time
It might have been a virus that caused the genetic shift in the cell, but at the same time it might have been radiation. As both are possible ways to evolve a species: i didn't take the time above to include those possibilities. Final note for homophobes: if you really hate 'gay' being in your jeans, perhaps it would be wiser to let them marry, thus ending the homosexual DNA strand that began advanced life on Earth?

Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day
