In the end it boils down to the problem that it's very hard to explain the mechanics of culture to people who have little to gain from changing it. When you've pulled the short straw in your culture, whether it's due to race, sex, orientation or something else, you have a lot of incentive to attempt to change culture and you logically end up spending a lot of energy on learning the intricacies of culture and cultural change. If you're in the priviliged group however there's very little incentive to pay attention to these issues at all, since effecting cultural change would have little personal benefit. A byproduct of those systemic forces is that it makes discussions between those two sides very difficult; quite like how discussing technical topics in politics is very hard.
