What you don't want is to hear about the view on the other side of that divide.
Moreover, Democrats argue on every issue under the sun, from Snowden to Obamacare, Hillary Clinton, and everything else. Yet some members single out the voices of people of color and feminists to denounce as too "divisive."
First people argue Democrats all already on racism anyway. It's an already settled issue. Then you say you don't like to see Democrats divided. These arguments contradict each other. They do not hold up to scrutiny since there are scores of others subjects around which people agree and disagree that you don't object to.
This strikes me as a demonstration of entitlement: if it's not about white men, they don't think is important or legitimate. Every time someone tells people of color, feminists, and members of other subaltern groups that there concerns are illegitimate or too divisive to be discussed, they only deepen that divide you want to pretend doesn't exist.
