I've mentioned this story here a few ties but it bears repeating, as it goes to directly to the question. A buddy of mine never wanted kids. He married a woman who also didn't want kids. They were doing fine until she demanded they have kids, which soured the relationship quickly. The divorce was bitter and ugly and not long after he met another woman who changed his life. He had his first kid at 40 and a second at 42. He could not be a happier man. I asked him if he regretted not having kids with the first wife and he said, "fuck no! She would have been a horrible mother and my kids would be 1/4 Jewish." There's the funny part. He now advocates for white men to marry Jewish women and keep them childless until they can't have kids, then dump them and marry younger white women. That's just too much work for me but it really is playing the long game for the species and you kinda have to admire the idea.
