Could social acceptance of homosexuality lead to decrease of the number of gay people in future years?

Partially a biology/population genetics question. But looking for any insights!

Assumption: homosexuality is at least partially determined by genes.

When a society is harsh towards gay people, more gay people in that society will stay closeted. As a result, more gay individuals will reproduce, which will lead to an increased amount of "gay genes" floating around in the population. 

When society is permissive of homosexuality, more people are openly gay, thus fewer gay people are reproducing, and following generations will have a lower prevalence of gay genes.

It's unarguable that we are witnessing a trend in America towards acceptance of homosexuality as a part of the culture. As society accepts homosexuality, and being gay becomes less stigmatized, will there be an inevitable decrease in the amount of gay genes floating around in the population, and thus a decrease in the gay population in future generations?

It's possible to imagine a periodic cycle, that society naturally works to maintain a certain average percentage of gay genes over time, and perhaps social attitudes are involved in this maintenance.

Is there any research about the way societal pressures participate in human population genetics? Like a kind of "social selection" rather than traditional "natural selection."

EDIT: I don't mean to assume that there is a single "gay gene" which if you have it makes you absolutely gay, and that gay parents will have all gay children. That premise seems extremely unlikely if not patently absurd. 

However, evidence shows there are certain genes linked to homosexuality. Perhaps multiple genes need to be present in a certain combination make an individual likely to be gay. People who have only 1, or only a few, of these genes would be "carriers" but will not be gay themselves. 

If this were the case, the child of a gay parent would be statistically more likely to inherit those "gay-linked genes," but since the child has another parent as well, there is a good chance they might not inherit any of the gay genes.

It is highly unlikely that homosexuality is an on/off gene. There have been genes linked to it, but it's not like you have that gene and you're gay. If anything, the idea of someone being gay or not-gay is almost certainly a societal construction and not really reflective of any kind of genetic information. Straight couple have gay children. Gay men and women are still entirely capable of bearing children and still do. Individuals can demonstrate homosexual behavior during one phase of their life, and heterosexual behavior in another.
