I think this is based on a false premiss - other than the Spartans, for instance, the toughest soldiers in classical Greece were in a Theban regiment composed of homosexual couples, and when I was squarebashing in the RAF some of the most macho corporals and sergeants were that way given (dreadful bloody thugs). A lot of military toughies throughout history have been homosexual, as have some very macho yobs like Hitler's SA. You are mixing up style and sexual orientation, surely?
