He needs to have evolved far enough to respect all people; men, women, gays, different gradients of color, different religions, equally. If he can, then that's a start. I can't think of one person I know that hasn't evolved (grown) on the acceptance issue. Even Rush can say "gay" now without that eye-popping quality that he used to invoke. It's a serious job, we need someone with military program awareness and some commitment to fairness for all the members of the armed forces.
Eccliastes 7:20 There is not a rightous man on earth who does what is right and never sins. Hopefully, we all grow and learn daily. Otherwise our survival as a species is suspect.
