defining the terms you're using is changing the subject? :freak:
ummm - no
and if those assumptions are based on fact?
for example - do a quick google image search on "olympic swimmers" and tell me how many of them are black
We're not asking about olympic swimmers, we're talking about hiring lifeguards. Who gets to the olympics is a lot less about raw talent than money and access anyway. Historically, black people were excluded from public pools because whites didn't want them there. There are fewer pools in inner cities.
This is a famous image from 1964, the hotel manager dumped acid into the pool to try and get an interracial family swimming together to leave the pool.
I can do a google search of nurses and find almost all of them are female. Do you think that means men are bad nurses?
I can see that there aren't many white sumo wrestlers.
Perhaps you need to understand that correlation does not equal causation.
