The use of bloodlines as a means to determine the content of character is a short-cut, it being much easier determine who someone’s parent is than determine how they will behave under pressure or temptation. Racists make similar gratuitous associations for exactly the same reason: they can’t prove or disprove someone’s character traits, so they make an assertion based on an assumption of a causal/property connection whose property (skin color) is easier to determine.
The use of programming terminology as a means of describing human behavior is probably fraught with hazards, but can be equally illuminating if done with care. For instance, if these memes are likened to programs running in the wetware of leftist intellectual brains, then how much of their effectiveness within that person is dependent on compromising what passes for the Arithmetic-logic unit? I.e. to be more specific, the comparator unit?
