But regardless, it's totally reasonable to criticise any system that discriminates based on age, height, weight, and so on. It's not right, and it can't be allowed to last.
Sorry carb, but with all due respect I just don't get your logic. By its very nature, any selection procedure will discriminate. That's its purpose. Where does one draw the line? After all, its only through luck that some people are born with an aptitude for flying that others don't have - that's discrimination.
I'd like David Beckhams' success and money, but through a combination of nature and nurture I can't play football like him. It's not right, and it can't be allowed to last.
