Some professions have minimal physical criteria that some women can meet. If she can meet the minimum physical criteria she can do the job. It is not discriminatory to set those criteria at a required level that only a very exceptional woman could ever meet… if that is what is required for the job. Even if the levels were set at a standrad that no woman could ever reach there would still be some men who could! In some sports women can and do out-perform men too. It does not follow that men and women should therefore compete together in all sports, men continue to have a marked biological advantage in strength and speed no matter how good the best women can make themselves.
