Based on data from the Southern Poverty Law Center (SPLC), there are 784 active hate groups nationwide. Hate group activities vary considerably, from verbal attacks in speeches or publications to the promotion of violence.

Via 24 Wall St:

White nationalist or white supremacist groups, including the Ku Klux Klan, neo-Nazis, racist skinheads, and neo-Confederates are by far the most common hate groups in the United States. And African Americans are by far the most victimized group of people by hate group activity and other, less extreme forms of discrimination.

In an interview with 24/7 Wall St., Mark Potok, senior fellow at the Southern Poverty Law Center, said, “segregation contributes to distrust between the races.” Dislike, intolerance, and hatred seem to diminish when people live alongside each other, and these attitudes are more likely to flourish when people are separated.

Not only can segregation damage race relations in a community, but also it has generated poor economic and social outcomes for many African Americans. According to Richard Rothstein, research associate at the Economic Policy Institute, federal housing policies in the 20th century are largely to blame for ongoing racial segregation and its economic effects.

For example, in the last 60 years, black families were intentionally excluded from affordable housing options across the nation. Since wealth largely comes from housing investments, and home values have increased dramatically over that time in many areas, those policies have exacerbated income and wealth disparities, Rothstein explained. Black Americans earn about 60% of what white Americans do, and accumulated wealth among typical black households is a mere 6% of the typical white household.

Those federal segregation policies, and the resulting economic fallout for black Americans, have contributed to lower educational attainment rates in segregated schools among other negative characteristics. These characteristics are in turn used to justify racist attitudes and can lead to white people fleeing suburban neighborhoods when black families move in. This happens even among ordinary people, who Rothstein said, “Don’t understand that these characteristics are not characteristics of the people but of the social conditions that [were] created for them.”
