I think you need to read the post again. It's not unreasonable to think that white males don't necessarily understand minority issues as they are vastly the majority in this community. He never claimed it was inherent or universal or even insurmountable. I don't even view what he said as negative, just trying to remind people of their potential biases.
Anyway, get off your high horse. We all stereotype, it's natural, and it's often very useful for seeing patterns in populations and hypothesizing a cause or correlation. There are definite trends that aren't just people stereotyping: men don't generally wear dresses, women don't generally go around topless to the same extent men do. Those are complete stereotypes that're pretty essential for understanding society.
