In college–where students are programmed to hate White people and all of our amazing accomplishments–I was taught by the lying servants of ZOG that blood, and race, are mere myths. It’s a constant contradiction between the lie of, “race is a social construct,” and the lie that Whites should feel guilty for being White while all other races are taught to be proud of their heritage.
Anyway, the matter of blood is biologically real and important to understand. We are shaped primarily by our genetics and then by our environment. To paraphrase William Gayley Simpson, it’s a waste to plant good seed on concrete as much as it is to plant poor seed in good soil. The ideal structure a society should follow is for the good seed (good genetics) to be planted in the good soil (a wholesome, fulfilling upbringing).
From the National-Socialist handbook, Faith and Action, here is the section on Blood:
You carry in your blood the holy inheritance of your fathers and forefathers. You do not know those who have vanished in endless ranks into the darkness of the past. But they all live in you and walk in your blood upon the earth that consumed them in battle and toil and in which their bodies have long decayed. Your blood is therefore something holy. In it your parents gave you not only a body, but your nature. To deny your blood is to deny yourself. No one can change it. But each decides to grow the good that one has inherited and suppress the bad. Each is also given will and courage. You do not have only the right, but also the duty to pass your blood on to your children, for you are a member of the chain of generations that reaches from the past into eternity, and this link of the chain that you represent must do its part so that the chain is never broken. But if your blood has traits that will make your children unhappy and burdens to the state, then you have the heroic duty to be the last. The blood is the carrier of life. You carry in it the secret of creation itself. Your blood is holy, for in it God’s will lives.
