LGBTQ increase as a reaction to overpopulation?

A more specific way to put it is, if there actually was some sort of genetic strategy for LGBTQ as a density-dependent response to overpopulation pressures (rather than some simpler default explanation like 'sex is a large mutational target' or 'antagonistic pleiotropy' or 'mutation load probably related to evolutionary-recent demographics'), that implies that overpopulation pressures + subsequent LGBTQ response have happened so many times before that a genetic strategy could be repeatedly selected for and refined and blindly evolved. The strategy has to come from somewhere. But the current human population & peak densities are unprecedented and have never happened before. There have not been thousands of cycles of human civilizations arising, developing or failing to develop large LGBTQ subpopulations, and then conquering or being conquered by other civilizations and their fitness decreasing/increasing and subsequent cycles being more likely to have a LGBTQ response. That is just not a thing, and in particular, it is not a thing we see now: LGBTQ percentages are not even positively correlated with country population growth. So such a group selection proposal really does not work.

(One can make a similar observation about the idea of transgenerational epigenetic inheritance having any meaningful impact on human complex traits: ...why? Why would evolution build such a complex mechanism to convey a tiny bit of information in a hardwired form instead of relying on the usual within-lifetime learning and adaptation and gene expression? How could any tobacco-specific epigenetic mechanism have arisen? Why would there be a famine/obesity program, since famines arrive frequently and short-term predictably long-term unpredictably, and not without warning once every 30 years like clockwork?)

I don't agree necessarily. People just blindly listen to what people say,  I disagree, I don't think people are born gay. I do think overpopulation is a cause for potential for diverted stereotypes. If we are over populated why keep breeding at the same rate, seeing all the kids without homes is enough reason to make me want to be homosexual just saying. I think nothing is predefined completely. I think free will is at the end of the day stronger then any "Genetic Aspect", to the choices we made in life. I don't just blindly believe something, I ask questions, where there is smoke isn't fire a person once said. No , where there is smoke is questions waiting to be answered and a path never followed before. That is love and attraction. Its a vague term, I don't want anyone genes or not, science, culture, stereotypes, to tell me who I can love and who I can be attracted too. I am attracted to and love a gay guy, I have never found a guy more attractive, trans now. What is the definition of love, science can only explain so much. I am not confused, I know who I love and I chose to love that person because I have a free mind, where love is free.
