I don't have the indespitable evidence because scientists refuse to talk about it for fear of having their reputations tarnished. There is a ton of scientific evidence out there but I'm not gonna bother posting it because you're just gonna say that because it comes froma "racist" it doesn't count. All the peoplewho believe in genetic differences have a tarnished reputation.
Here's two things you're not realizing. First off, scientists do NOT have any proof that all races are the same on an intellectual or behavioral level. They will only say theres no solid proof for either side.
However they may mislead you and say things like, different races share virtually the same DNA. But that's a misleading statement because we already know that it only takes a few genes to make huge differences in the body. For example it only takes one codon (which is a fraction of ONE gene) for someone to have sickelcelled anemia. Blacks are more likely to have this than other races. So that is an example of a trait you see among one race more prevalent than you see among other races. And it is due to only ONE gene. So the notion that we are all virtually all the same on a genetic basis doesn't mean anything.
The second thing is that you are assuming, for whatever reason, that the default position is for there to be no behavioral traits you find more prevalent among one racial group over another. Why is that the default? It makes nosense and I can show you why.
You agree that Asians are more likely to have smaller pensis than blacks. Some may have ten inch pensis, but the average asian has a smaller penis than the average black.
Then average asian is shorter than the average black.
Blacks have a genetic advantage when it comes to the 100 meter sprint. No white man can ever beat the top black man. This is clearly because the African has a genetic advantage.
Blacks are more likely to develop high blood pressure than whites.
Blacks and asians are more likely to age well than whites.
Blacks are more likely to have fuller lips, breasts, and butt, compared to other races.
Some races from Europe are more likely to have bad teeth because of a gene that makes it so their saliva doesn't have the proper enzymes to kill bacteria.
So you agree, whole heartedly, that there are physical traits you are more likely to find among one race over another. The basis for these physical traits are the genes.
But for some reason, mother nature decided to build an invisible wall. Mother nature said let there be physical differences, EXCEPT for the brain. For some reason you think all racial groups have the exact same brain, even though so many other things are different.
And the funny thing is, you will probably agree that blacks have more RHYTHM than other races, like Asians for example. Where does this rhythm come from? You honestly believe it's 0% genetic and 100% environment?
So if blacks can have a mental trait that others are less likely to have, like rhythm, then why can't blacks also have behavioral traits that others are less likely to have.
wtf is this 
just a heads up, your beliefs are based on "emotion" and not science or logic. expect for that to be pointed out whenever you ever mention your beliefs to anyone again
many of your beliefs and idiotic unfounded claims of black inferiority follow you around this forum like a skunk.
