Again... If THIS ☝️has been what's happening... And society is collapsing or deteriorating... Then how can you make the claim that the best genes are reproducing?
Hym "Dual gene theory? Jesus Christ... 🤦 ♂️ No. 'The best genes' is clearly just a euphemism for 'fat cock'. Really. It's just... It's getting pathetic at this point. 'Women are trying to find the most competent man' or 'Women are looking for the best genes' give me a break. They want free money so that WORK is optional and to fund whatever enterprise they want to engage in. And they want a fat cock. In their pussy. But not ALL the time. Cervical orgasm wears off after a while, remember? No Cervical orgasm and what are you left with? Just the piece of shit useless retard. Like the cripple! Or Tyrone!"
