Racial discrimination in sport

Active racial prejudice by sporting authorities
Prejudicial treatment of sportspeople on ethnic grounds
Although it is now illegal to refuse membership to all, many exclusive golfing clubs in the USA do not have other than white members. Rather than accede to the rules of the Professional Golfers' Association and accept black players, one withdrew from a major 1991 tournament. The club said there were no discrimination clauses in its by-laws, but did not have black players (nor Jewish, nor women).
