Do you think black people are better at sports than white people?
No.
Do
you?
See the problem with this kind of thinking is how utterly overly-simplistic it is. It is commonly known why African-Americans in America play sports, historically, rather than say, look to work in other areas -- because sports, music and entertainment were open to them, again
historically speaking, long before other opportunities were.
You won't learn about this by watching YouTube videos and reading Reddit/4chan; instead, you'll get someone's interpretation, who likely lacks an education to formulate such an opinion, based on their anecdotal experience.
"Oh look, there's Black people in sports, they're good -- that's what they do well, then." "Asians do well in school, so it must be because their brains are better at .. stuff." "Jews ... whatever, run the world or some nonsense;"
This is called correlation without causation, which is a phrase I'm sure you've heard in your lifetime.
Black people are in sports because of the history of keeping Blacks out of decent paying jobs. Asians do well in school because of a cultural shift post-World War II and an embracing of not only education, but that coupled with a culturally mandated responsibility to take care of your parents and even your larger family which dates back hundreds of years.
There is no, biological, or genetic trait, shared by all Asian people that makes them study hard in school. It's a cultural aspect of many (not all) Asian cultures that is largely enforced within the household; an aspect that is less emphasized in other meta-cultures.
So with that said, it's important to understand that society does not change overnight. And just because you might have started paying attention to the world around you recently, doesn't mean that you've figured it all out by looking at the world through a racial lens.
Scientifically speaking, race is a social construct; it is
not biological. So to argue that "Black people" are better at sports or that "Asians" (in a generalized sense) are better at some thing, whatever you choose to stereotype Asians as doing, is a sign of pure ignorance.
And what's most startling is that to repeat this claim, after being corrected numerous times, is either a sign of unmitigated stupidity or stubborn racism - or perhaps both.
It might be a good idea to stop reading whatever content you're ingesting that's reinforcing these racial attitudes, and instead start applying some critical thinking to these .. rather asinine .. conclusions that you've come to.
