It's neither - it's a simple matter of taste. A person's taste in food is really not important - why is their taste in sex so important?
Eating and sex are both bodily functions. If someone really likes chocolate ice cream and really hates strawberry ice cream - is that choice in taste so over-poweringly important? Would we some up with a term to describe that person? Would we call it a "life style"?
Of course we wouldn't. Why is taste in sex so much more important in taste in food?
When you meet someone do you say, "Hi, my name is Mike and I like Chinese food."?
Saying, "Hi, my name is Mike and I am gay" is just as ludicrous to me.
I don't know why both homosexuals and fag-haters BOTH seem to think this matter of taste is so darn important.
When I meet someone I couldn't care less what kind of food they prefer - nor do I care what type of sex they prefer. Why would I? And why would anyone else?
Those who claim it IS important because of what the Bible says - remember the Bible mentions what food we should eat and not eat more than it mentions what kind of sex we should or shouldn't have.
Frankly, both the "gay" crowd and the "anti-gay" crowd are both guilty of making a mountain out of a molehill.
Unless I am planning on having sex with someone - why would I care what their taste in sex is? Unless I am planning on preparing a meal for someone - why would I care what their taste in food is?
And why is there such a difference between the tastes in two bodily functions?
(If your answer to that question is "the homosexuals indulge in 'unnatural' and dangerous sexual behaviors like oral and anal sex" - remember far more heterosexuals indulge in both of those behaviors than homosexuals. The sheer number of heterosexuals make that so. Also - some people eat things others would consider "unnatural and dangerous" - again, why would anyone else care?)
Because it defines the environment in which their children, society's children, grow up.
And that, as they say, is the ball game.
Well, to the extent that you can believe any studies...the studies that have been done suggest that this is not so, especially as relates to the variation of partners.
As a side-effect, there are numerous diseases that are so much more prevalent in homosexuals, that derive from sexual behavior, that they are regarded as markers of homosexuality. The famous LaVey study that purported to have identified a difference in brain structure of homosexuals didn't know the actual homosexuality of the subject, but rather derived it from the diseases the corpses had...and there was no significant argument on that account.
Before the federal government stopped doing the studies, the evidence suggested that the average homosexual had sex with roughly 7-8 times as many partners per year as the average heterosexual did in a lifetime.
