I don't know the stats off-hand but I imagine there's more MTF trans than FTM and I imagine the prevalence of gay is higher than lesbian.
By pushing the LGBTQ+, my hypothesis is that is removes more men seeking women from the dating market than it does women seeking men. Thus the supply of men is reduced and the demand for women is reduced as an overall impact of LGBTQ+.
Thus, were LGBTQ+ to not exist, would that make it even harder for straight men to compete for women?
Women are only interested in the top 10 or 20 percent of men. The rest are paypigs to them at best. Even if you're correct in assuming that the alphabet people take more men than women out of the straight dating pool (an open question) the men being removed aren't the top men that women are interested in. Chad Thundercock's life is going great. Unlike a Faggit janny he doesn't need to trans himself to gain social power. None of the men who pose serious competition in the dating market become alphabet people. Alphabet people might make it marginally easier to become a betabux deluxe but who needs that shit?
Yeah, this seems the more likely scenario.
