I don’t have a problem with Sikhs wearing turbans in the U.S. military. I want them on our side since they’ve been fighting Muslims for hundreds of years now.
Then you shouldn’t have any issues with bearded orthodox Jews, bearded Muslims, tattooed and heavy set Polynesians either... And why not? Ever since we opened the door to women in the military, we had to create double standards in grooming, uniforms, height weight standards, fitness tests and all sorts of waivers or just doing away with the standards outright, because otherwise you wouldn’t have any women qualify.
There is more than one meaning to the word “Uniform.”
Von Steuben professionalized the US military and made it into a cohesive fighting force in the war of independence. Drill and ceremony, marching, a uniform, customs and courtesies, group fitness training, even the buzz that all recruits get serve this end. Battles are not won by individuals. The enemy will not be impressed by our diversity.
