Prove it. With evidence.

There's plenty of evidence that being gay is at least somewhat related to their genetics (which would suggest they are born gay).

I read a very convincing post that homosexuality is a product of evolution.

There's plenty of heterosexual males that have more feminine features.

That assumes that the sample is representative of the population.

If they picked 50 gay men, and 50 straight men, the accuracy of an "always saying straight" algorithm would only be 50%.

This part in their notes suggests that it's not quite that simple:

"Back to the group of 1000 men, including 70 gay men. If one selected 100 random males from this sample, only 7 are expected to be gay: a random draw offers a precision of 7% (7 out of 100 selected men were gay). Let’s turn on the classifier. Among the 100 of individuals with the highest probability of being gay according to the classifier, 47 were gay (precision = 47/100 = 47%). In other words, the classifier provided for a nearly seven-fold improvement in precision over a random selection. There were also 53 “false positives” - straight men classified as gay. Note, however, that as there are only 70 gay men in the examined population, there would be 30 “false positives” even if the classifier was perfect. "

Fair enough.  Wonder why they didn't cut it off at 70 then as that would have made more sense.  I'm curious what the statistics were for 1-70 and 71-100.  Seems odd to guarantee yourself at least 30 false positives.  Especially when you're touting accuracy.  It's the sort of thing that makes me think the numbers were massaged a bit.

That's not all that impressive in context.  They could have gotten a much more accurate predictor if they'd just had the algorithm say "straight" every single time.  Then the accuracy would jump up to around 95-96%.

 Nem said: Erm... it's been scientifically proven that it is genetic. So, yes, you are born into it.

No it hasn't.  There's a correlation to be sure, but humans are complex creatures that are a sum of their genetics, experiences, upbringing via parents, cultures, traumas, successes, support structures, social status, opportunities, etc..

Any all or nothing statement on why people act and want what they do is faulty (and in this case a politically motivated myth).  It's never as simple as nature vs. nurture for anything.

I never really understood why the question mattered anyway.

If you're not born with it, that would suggest that there's a choice involved. That just doesn't seem to be right, if you think about it. Do you feel that you could just choose someday to go the other way? I couldn't. You like what you like.

Does that work on people who repress their homosexuality?

“It appeared that there had even been demonstrations to thank Big Brother for raising the chocolate ration to twenty grams a week. And only yesterday, he reflected, it had been announced that the ration was to be reduced to twenty grams a week. Was it possible that they could swallow that, after only twenty-four hours? Yes, they swallowed it.”

There's several studies that make it very obvious. Or are you expecting there for be human experimentation?

The homosexuality has to do with a hormone balance.

It can be resisted though. There's several gay men with children. Honestly, i think a man can get hard to virtually anything. But it should be obvious to everyone that it's genetic when there's a lot of people who don't want to be gay but simply are.
