Explain me.
Look it up, it = written on this board 100 times.
Yep.
Not all blacks have an 85IQ, obviously. Just like not all whites have a 100IQ. But when you consider averages, skin color is a likely first indicator when dealing with someone you don't know yet. Superimpose "black culture" over the whole IQ issue, and chances are even if the person isn't a complete moron from an intelligence perspective, they are still someone you don't want to associate with. Once you get to know a person, you may find them to be an exception to the rule, but that doesn't change the facts when dealing with blacks in general.
Exactly. At the same time, their culture = probably partially a result of their low intelligence in the first place. If you see culture as a system of chaotic interactions with initial conditions set (the avg. intelligence of each unit in the system for example), then these initial conditions will still participate in determining the outcome of the system regardless of outside influences (like racism), at least when enough time is given. Blacks tends to spiral down and down and down, while more intelligent races tends to get themselves up from the gutter eventually. Claiming that "they are still recovering from slavery" = moronic.
