I think it's fair to say that at least a sizable majority of black-identity "leaders" are exactly parallel to white identity "leaders" - bigots no different from the Nazi party leaders. The problem isn't the existence of trans-racial black leaders, it's the existence of race-leaders at all. MLK had it right - judge others by the content of their character and not by the color of their skin. Identity politics merely extends racism, which would otherwise already have died a natural death.
We have Federally recognized (and enforced):
- National Caribbean-American Heritage Month
- Black History Month
- Hispanic and Latino (and Latina) Heritage Month
- Pacific Islander Month
- Women's History Month
- Native American Heritage Month
- Gay Lesbian Pride Month
- National Disability Employment Awareness Month
And a slew of others.
If you proposed a "Men's History Month" or a "European American Heritage Month" they would place you in front of the cultural firing squad.
