I believe it's bs, but I'm pretty sure my parents won't listen when time comes, I guess I'll just have to do that expensive procedure of surrogacy paying foids for egg and carrying baby
your DNA over time
you plus woman you impregnante = 50% her genes, 50% your genes
next gen = 25% your genes
next gen = 12.5% your genes
next gen = 6.75% your genes
thats just 4 generations. this means, within your lifetime, if you start having kids early, your DNA, your "blood" will be extinguished basically.
You could be grand-grandparent and your newest offspring would only be 6.75% you and 93.25% someone elses DNA. Since one generation is usually taken to be 25 years, this whole process of DNA dilution only takes 100 years. Now imagine 200+.
By year 200, your remaining DNA will be like 0.8% or even 0.4% of your descendants. It's a meme.
Also, of course this is hyper simplified. If we factor in epigenetics, external influences on DNA from radiation, toxins, diet, disease - then it gets diluted even more.
Besides that, all of these retards talking about bloodlines are incapable of forming coherent groups that last for centuries, since they are hyper-competitive men who only care about defeating other men in the rat race, so they are actively undermining any chance of having a lasting legacy while larping they want to have bloodline for millennia. Protip, if you hate other men and constantly obsess over mogging them to get pussy and status, then your blood, your sons will inherit this and start hating you and shit on your bloodline.
Thats what we see with boomers and current gen, almost nobody respects their parents, let alone father, because they are not respectable people, they are across the board retarded selfish assholes and worse, they think its virtuous to be that way. They kick their sons out at 18 with smug face and call it shit like "tough love." Same niggas later complain that their own flesh and blood hates them and that they will die alone.
