Did you read the paper you linked? Or did you just post it because you think the title of the paper proves something?
I used it as an example of an academic source using the term racial dimorphism.
I just googled the shit out of dimorphism, dismorphic, and racial dimorphism and that paper is the only one I can find.
Then you clearly aren't that good at using Google.
With a quick search on Google, without any serious effort I was also able to find:

And so on.
Dimorphism is a word in its own right, which does NOT simply mean sexual dimorphism.
Sexual dimorphism is a type of dimorphism.
It is not "social conditioning" to know that men are different from women.
It is social conditioning to think that discrimination on the basis of sex is acceptable, while equally justifiable discrimination on the basis of race is seen as not acceptable.
It is also social condition which leads to some of these differences, e.g. men being expected to carry more and hold more weight building more muscles while women carry less building less muscles.
It is not social conditioning to know that men are stronger and faster than women.
On average, just like black people are faster than white people, on average.
It is not social conditioning to wish for women to have the opportunity to play sports without having their skulls cracked by men.
While you think it is perfectly fine to have their skulls cracked by women, and for men to have their skulls cracked by men?
Certainly sounds like social conditioning.
Nothing is stopping female athletes from competing against other athletes of similar ability.
Just against those of similar ability that aren't female.
I have no idea why you think this is somehow sexist.
Because it is discrimination on the basis of sex.
That is quite clearly sexist.
If you were actually using ability, there would be no need for things like humiliating sex testing at the Olympics, which have caused some people to commit suicide, and others to undergo questionable procedures.
Also, you should make up your mind. Have black people evolved so differently than white people, or is selection artificial?
Different races have evolved differently in the same manner that different sexes have.
They filled different niches and as a result, different traits were selected for.
I'm beginning to think that JackBlack doesn't understand basic human behaviour.
Why?
Because I understand how modern society has been conditioned into thinking that most forms of racial segregation are discriminatory and unjustified, while they have also been conditioned to think that similar segregation based upon sex is acceptable, even though it is no more justified?
I understand it quite well.
How people here need to dodge the issue of race and pretend I am racist or sexist to avoid dealing with the issue just further supports that.
If the answer is yes, then how is it bigotry to know that humans are racially dimorphic?
Other than it being complete nonsense? There’s nothing remotely dimorphic about race.
The only way in which it fails is the "di" part, as there are more than 2 races.
But races are different, just like men and women are.
If that doesn't tell you we need to end women's sport, I don't know what will.
Again, are you capable of addressing things honestly?
Did I use that at all to try to indicate we need to end women's sport?
No! I used it to demonstrate other usage of the term racial dimorphism.
Did I ever suggest ending women's sport?
No. I suggest removing the sex based segregation. Women would still be able to play, they just can't unfairly exclude someone on the basis of their "sex". (In quotes because of the often arbitrary tests used)
It’s a shame he can’t see the difference between discriminate and differentiate.
Have you read a dictionary?
discriminate: recognize a distinction; differentiate.
Discrimination is literally distinguishing between 2 things and treating them differently because of it.
The question is if it is justified or not.
This also leads people to adopt a slightly different definition, where they add on the discrimination being unjust or prejudicial, and focusing on people.
But again, the only way to try claiming such discrimination is justified is if you claim there are different ability; but that instantly opens up the possibility of using ability to discriminate and place people into different divisions, instead of using sex.
Or why there may be cultural aspects to why black Americans and Afro-Caribbeans came to dominate sports
Similar to how there may be cultural aspects to why males dominate sports?
