There is a vast difference in denying racism and previous State/country supported racism that was existent in the USA till the 70'ies - and claiming that this previous State/country supported racism is the reason for today's US Negro society and it's failing.
As such people who live in denial of existing personal racism and previous State held/country supported racism - off course are a valid reason for e.g.
IM2 to go onto his warpath - he automatically becomes an inherent racist himself via constantly propagating that all Whites are racists, and that today's failing of the US Negro society - is solely due to a previous State/country supported racism.
Are we clear now?
