This book, along with Steven Pinker's book The Blank Slate, has grey-pilled me

I know how much you niggers love twin studies, a lot of their arguments are made from looking at twin and adoption studies.

Beauty is a personal (although most White people agree that niggers are indeed ugly).

But also niggers have a MUCH higher chance of carrying STD's and have generally be proven to be unreliable for fatherhood except those from the higher classes (= strong minority).
Stereotypes from fatherless niggers come from somewhere.

Also they are genetically not adapted to a life on the Northern hemisphere, they are less healthy here because they are built for life in the jungle or desert.

He's correct on that. Children belong to the mother's family in most hunter-gatherer societies, men often don't even know who their children are.

The biodeterminist argument is that those outcome differences come from the parents' shitty genes, which are also what caused the homosexuality/divorce. This is partially true (there's no "gay gene", but there probably is a gay germ, and pathogen resistance is affected by genes like everything else). However, over the long term it doesn't actually matter whether the kids turn out shit because the genes are shit or because the lifestyle is shit. If you favor that lifestyle with policy, you alter the selective environment to favor those genes. This is what the biodeterminists typically don't get when arguing policy. Yes, that single mother's kids probably would have turned out shit even if she had married one of the fathers. The difference is that if we weren't subsidizing single mothers they'd have fewer kids.

Oh it's the "culture, not race" argument. Welcome to Holla Forums, Sarcuck, there's the door.
Why, tell me, have only the Caucasian and East Asian people managed to build and maintain a civilization? Are we just lucky that we have such a great culture?

some twin studies had one twin be straight and another become gay. So you are correct, it's not really genetic. Pinker attributes it to some chance event, probably during brain development.

Intelligence would allow you to resist or reject ideas like that. Again shaping culture like sheltering these ideas from your kid which shapes their environment.

It's both. Even this book states that.
A White who was raised by a single mother is likely to have a high IQ, regardless of his culture, but the life-opening oportunities he would have are gone. Also, he will not have a role model to tell him how to dress well, eat well, be healthy, etc. Also, his childhood is prone to lacks and bad experiences due to absent of directions.

Similarly, a Nigger from a wealthy nuclear-family is likely to have a lower IQ than the White guy, but he will study in prestigious places, and will have doors opened in his life. His family will also provide him with financial and social support. He likely would have a happy and carefree childhood as well.

Is Mental Gymnastics going to be in the next olympic games? Because leftists would completly dominate it.

I just want to take the chance in this shill thread to dump a thought on races i habe had. What if in the future it comes to light the differences in races extends beyond hair eye color bone structure intelligence brain size and athletic ability. What if also it turns out we experience emotions diffrently? What if we don't even have the same emotions? Certain animals cannot have fun or feel love. Is it possible niggers cannot love or feel joy the way we do? Could this explain why they only try and fuck and chimp out all the time?

Intelligence would allow you to resist or reject ideas like that. Again shaping culture like sheltering these ideas from your kid which shapes their environment.
