I ain’t from DC, but spent hella time in the District 10+ years. There are two DC’s, native black folks vs. everybody else. To be honest, all other groups in DC give off an arrogant anti-black vibe. Non-blacks in the DC area literary think being white or acting as white as possible is the key to success in life. Look at famous cornballs from Montgomery County like Logic and Roosh V and tell me I'm lying.
DC used to be the chocolate city, the blackest city in America. Many DC natives don't care about the culture of other people or places because DC has it's own very distinct culture (i.e. Go Go music). Black DC natives are like an indigenous tribe with their own way of life and customs.
Whites and non-blacks in DC are mostly from other places. Aside from a few old money cacs from Georgetown and Upper Northwest and a few Africans and Centro Americanos here are there Uptown. Colonizers come to DC and have no respect for the local black culture. That's how Go Go music damn near got cancelled in DC. All it took was one phone call from a Karen near Howard U.
Northwest DC west of about 13th St, Montgomery County, MD and Northern Virginia is full of cacs and non-black people who are essentially global tourists who think they are cultured because of that. These people are rude, overly sarcastic and believe in soft white supremacy and respectability politics. These people are always "on"; always have something covertly sarcastic and nasty to say like they have Jewish screenwriters and shyt. These people never work with their hands. That's what the Salvadoran slave class is for.
Most black DC natives are cool if you get to know them, but they generally don't like outsiders. Can you blame black DC natives? Black DC natives know if you give them an inch, they'll take a mile.
