This is actually what got me banned from Reddit. I engaged in "gender essentialism" by saying men and women have different priorities based on their sex.
I will tell you how it works. Evolutionarily speaking, intelligence is the capability for lifeforms to adapt during lifetime, instead of having to rely on thousands to millions of years on slow, arduous genetic shifts that are largely directionless. The higher the intelligence, the better this runtime adaptation works. The lower the intelligence, the more an entity is reliant on its nature.
What this means: Niggers are low intelligence, thus the possible variance in personality is very low. A nigger won't be an architect, engineer, programmer or whatever not only because it can't, but also because even if it has been "groomed" its entire life to "make something out of itself", it won't - or rather there is no societal environment that would encourage it anyway. Its parents were low-IQ niggers who beat the shit out of their offspring, and don't give the slightest fuck about them. Its nature is to be a parasitic thug, and it's ideally poised to be that.
Both, the range of options themselves and the range of personality depend on intelligence.
Humans however *do* have the ability to be different. And no, it doesn't depend on nurture (parenting) directly, there are many factors that play a role. A person does have an image of people in his societal vicinity, which he seeks to either become himself or revolt against it.
On the other hand many parts of the personality are determined by genetics. You thought you are a stubborn asshole who hates niggers and faggots just "randomly"? Like this fate befell you? No. If it weren't about those, you'd have picked up another fight.
So for humans it does play a role, but less than people think. For niggers however it's near irrelevant. The variance is as much as for dogs. And a lot of their behaviors are inherent to how they are, not how they were raised.
it's true to some degree. the reason why so many people lean into it is because our society generally views any trait or aspect you were born with as something off-limits for criticism or exclusion. to weak minded people, it's an excuse to basically say "can't blame me for it!"
You could take this argument to its logical conclusion and say free will doesn't exist. Which I personally do. And I try to ignore it every day because the implications of that conclusion are distressing. :/
