I have made contact with some in the Prince Hall. I have emailed the lodge in my town and no luck in getting a response. I am not make assumptions about the organization I am just saying about my area, and I feel that the way whites and non-whites interact may translate into the organization. I am located in southampton, va.
Freemasonry should be colour blind, all that should matter is your character. Sadly, some Freemasons fail dismally there, and in some places, whole lodges do and even Grand Lodges have, but you obviously done some background reading on this issue.
Just remember lodges are run by volunteers and are not a business - it can take them a while to respond. That can be true even for freemasons trying to contact them.
As Rip alludes, other threads recommend you just go knocking at the door, but don't assume anything about the character and composition of your local lodge until you actually find out... if they are racist, you don't want to be in them. If my lodges were racist, I would not want to be in them.
But don't expect the worst ...
I'm in Australia but I'm sure more American bros will chime in.
Every success in your quest!
