Well intelligence is partially hereditary, and childless men won't be passing on their genes, so I counter that these men really aren't as intelligent as claimed.
Hmm, I guess we found the breeder?
Not even sure where to begin with this, circular reasoning?
Have you perhaps considered that these intelligent people have considered tgat passing on their genes is not as valuable to them as other things they might value? I'd posit you haven't, and further, you shouldn't consider yourself among them.
Nor do I consider myself particularly intelligent, making you 0 for 2, and it all the more wonderfully ironic if you considered yourself amongst that group.
Also your circular arguments towards childless men being stupid while also being a self-proclaimed "stupid & childless man" is poetic and somehow makes sense to me.
