A person has to live for several years, every day , in a role/with an identity where the dominant, overriding societal attitude might disempower the value of that role to other more powerful, socially acceptable roles OR stereotype that person.
A good first step is just to realize it is possible that the view you hold of race as a white person could change if you got to experience life through someone else's eyes. (30 days is a great tool for that.) I often encounter this inability to empathize or to consider that someone else could see things differently when it comes to race/gender, etc. I wouldn't be exaggerating if I stated it is 99% men who I encounter with this inability to empathize.
