I remember when I was in Iraq I sat in a guard tower with one of my bros who use to hate Mexicans and blacks, he grew up a racist and he told me "You know what Parra you're one of the coolest people I met, loyal to death and I never thought I would say that about a Mexican." And I told him, "It's because you were raised to think that way, but people bleed the same shade of red." And he said, "You know what bro I would bleed for you." And I replied, "I would too. Race means nothing when we are both green, and when we got each others back and when we are brothers."
When I was in the military I realized race means nothing, but the culture you build together is everything.
