Look, this is getting rediculous.
Do you understand the concepts of proof, truth and proof positive?
Do you understand the difference between a theory and a fact?
I have read all your posted links here, and guess what... They are crawling with formulations such as these:
"It has yet to be proven, however [...]"
"...the research will not be accepted as valid until others replicate the experiment."
"though no specific conclusions may be drawn yet"
In case you didn't know: Quotes like those mean that something is not proven, that something is a theory and not a fact.
The articles you quote have something else in common too.
First, and most important, they all say that the results of their research needs to be replicated before being accepted as a fact. I e they have not even yet proven that the anomaly exists. Then they say that even if the anomaly is proven to exist, it is uncertain what that anomaly would have to do with homosexuality.
If you combine those two, and try to rephrase it, you would get something like this:
We think we have found some anomalies, but we are not sure yet. First, we need to make some more experiments to make sure that the anomalies we found are not just some random event.
And these anomalies we think we've found might have something to do with sexual behavior, but we are not sure. The reason we think that is because we have found these anomalies in some gay people, but not in all gay people, and we cannot explain why that would be. But since we found the anomalies to be occurring more often in gay people than in straight people, we think that means something. But we are not sure what or how.
Now, let me ask you. Do you consider that to be evidence, proof positive? Because clearly not even the scientists you are quoting think so.
