What makes a person a bigot in people's eyes in these cases is to bring up IQ, a measurement that has a lot of connotations to innate ability. Bringing up lack of innate ability in the context of race will quickly get one labeled a racist. Now, that might be unfair and rash, and people may have a misconception of what IQ is. But the rules are pretty simple: don't allude to things that have connotations to innate ability, and you will at least have dodged the biggest bullet. If you had not brought up IQ, and instead educational opportunities and such, there would have been no controversy. Yes, black people are in worse position than white people when it comes to education - this is very uncontroversial. No need to bring up things like IQ in order to make that point.
