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?
This is the dominant subjugating the weak.
Dominant figures more successfully spread their genetics if they sabotaged their sexual competition.
They're hijacking the psychology of this - they're not technically doing this for the most part because they're just replacing the current people here with people from poorer countries that grow up more normally and have fewer pyschological issues - and passed a fitness test to get into the country.
The idea of sexually controlling the people below you is appealing to dominant personalities that view themselves as the people in charge.
They're pushing 2 things simultaneously.
