That's better, and yes, of course implications matter. Still, outside of context, Bell could mean that "a substantial number of white people will always be racist". All is a very high bar, even for implication. (I don't know whether Bell does the "racism is only racism when white people do it, ostensibly because I like the definition that requires nationwide institutional power" thing; that also is relevant here. But even if he fully endorses that view, the quotes despair of a solution, but don't specify the fraction of perpetrators.)

So I still don't think you've made your case very clearly with regards to Bell. With the others, I think implication covers it.

("All" doesn't have to mean 100.00000%, just "any exceptions are rare enough to be neglected for all practical purposes".)
