No

How can you even apply the crab in a barrel mentality to this?
You don't think they were protecting their own?
You don't think they helped contribute towards the diminishing of Lynching through activism and other means?
What could they do if a white mob came at them? Nothing.
They even lynched white people who tried to stop them from lynching black people (I think it's somewhere in the 1,000's for how many were lynched for that) so what chance do you think a black person had?
They had no proper channels to go through for help and even if some didn't help can you blame them for not risking death and torture and every thing dear to them?
You have to be a troll.
