Is there anything more redpilled than cucking someone? Fucking YOUR baby into into HIS wife/girlfriend so that that you get to pass on your genetic legacy and his bitch ass has to raise it? You get to produce progeny, and someone else will take care of them, leaving you free to go on and do other things, like produce more fucking progeny. And on top of that, you help to make sure that the little faggot doesn't get to pass on his shitty genetics, ending his pathetic lineage before it can go on to cause any more damage.
So the dude wants to raise his wife's son, help him out! And if his wife ever wants any more, make sure to be on call! It's your duty as a man. Never turn down a woman who asks for your DNA to help make her child, especially if her meal ticket sanctions it. The cuck is a gift to all of us. It's the ultimate redpill, faggots!
