But on the complete other side to that black people are the only race that I have actively noticed who feel the NEED to say hello to another person who is a complete stranger just because they are the same race!

They can be in a completely different country to where they live so they blatantly don't know anybody but when they walk past a fellow black guy they have to acknowledge each other. It can be just a simple and discreet 'up nod' or a straight up full blown greeting but there will always be something.
This is hard to explain if your with a group of white people in a foreign city and you acknowledge a black guy who has clearly acknowledged you but not any of the non blacks in your group so they ask if you know him! (which you don't).
This happens more in the UK but it does happen all over the world. I think the reason may be down to often being in the minority so black guys subconsciously look for support in numbers whenever they get the chance.
This is only true of the black men though, black women do not greet strangers just because they are the same colour.
It looks like even Obama has some form of this built-in black on black welcoming thing going on too! (check the video)
