Pretty much all successful social/justice movements start with galvanizing internally. A broad consensus. You don't need everyone. You need a certain percentage (and that can vary) where being on code is the acceptable behavior and those off code are ostracized, excluded as 'punishment'.
You guys are from the UK and that has some similar issues all Black people face but also unique to the country. Tariq Nasheed said his biggest support outside America is the UK. Which I'm guessing is why he was banned from the country.
The UK was also the country that had the biggest BLM marches outside America. Kudos.
I haven't spend enough time in the country to know how much unity there is. I'm guessing it depends on the area. London as opposed to other cities like Birmingham, Manchester, etc. The Brixton, Streatham area where I stayed was like being in Brooklyn, southside Chicago..lol
My 'spider senses' were tingling a bit because there was some hard looking brothers there. haha.
