So you're wanting to reach out, that's good.
I disagree on "we don't get to do that"...plenty of black men chop it up and build. I think the issue with you is, you're carrying the cross while trying to make 'frends' and just connect with people. You say you've been given all this clarity about the structure, like you're seeing the code.
Seeing the code is step one, manipulating the code is the next step.
Not to say ever be apologetic for your thoughts, you writing them down is awesome in and of itself but the fact that you couldn't find the space to approach your brothers means you were leading with the wrong energy, the wrong state, tuned into the wrong station. State control is paramount, with the right state/mental resources you could have been building/networking with these cats instead of subjecting yourself to negativity on the coli.
Meditation is wonderful but It took me a couple years to really realize that I wasn't just supposed to escape, It was entrainment to the void, to peace, to neutrality so as to move forward with the will free of impediments like childhood stuff or 'black plight'. You gotta bring that with you once you come back, you have to learn how to meditate life.
I would say, while still in a meditative state...anybody you see that you would like to connect with, you should pre-meditate the sentiment. You sound like you just wanna show love, you can do that without saying a word or shaking a hand. You generate those feelings for yourself and then approach. You'll be surprised how your interactions with people change when you are actively participating in setting your emotional baseline.
