if the stereotypes are not true how do you explain that certain sports are dominated by one race or certain activities by another ?
Canada is one of the most diverse counties in the world , why are they sending only asians to the math olympics ? Are they racists?

Certain cultures value learning certain skill sets over others.
If all it took was money and athletes then the Americans would already be a football powerhouse.
If some people are taught from birth that they need to study maths... and others are taught to play football then one group will do better than the other
however, if the situation was reversed then you'd see the opposite culture dominating over the other.
People think of Asians as more incompetent than whites or blacks at athletics... yet China, Japan, and Korea placed third, sixth, and eighth at the Rio Olympics.
This is because in America, American football and basketball are the most popular sports so there is more value and social capital mastering that over something like figure skating.
I'm sure it's similar in Europe where Asians have been disparagingly referred to as shirt sellers.
Fortunately players like Son Heung-min are slowly changing this image.
I think it's fair to say that in sports where sheer size is important like American football or basketball... certain races might have an advantage because of height or weight advantages... but in most sports like football... the differences will be mostly cultural rather than race.
If you are given a football at two years old... you will be better than an American who doesn't play until eight or ten years old... who never watches it on television with their fathers.
You will also be better than some impoverished third world nation where they don't have a proper ball, or goal, or grass for their pitch.
There are a lot of reasons why there are differences... but most certainly in the case of football where size isn't the most important factor it is because of cultural differences and preferences rather than race.
