OP, I get that you are not a native English speaker and might not know that the term you used is a wildly offensive way to refer to people of color, but your assumption that Black kids are all good at basketball is just as offensive and can’t be explained by language.

Do you also believe that all Asians are born good at math and all white people are born knowing how to swim and play tennis?

Huh?

It is for recreational and weekend only. We cannot do any weekly practice during weekday now due to tight schedule, and I have a boy that has not played either of this sport.

I have heard about pat the rock academy for basketball, and they have weekend class only. I am hesitating because all photos from their websites are mostly colored from kids to coach, does that mean they are not for recreational & newbie level?
