I haven't experienced a lot of issues with black people who aren't American but I've been aware of tension and prejudices between the two groups since college.
Don't understand the pridefulness of either group, especially those that leave home to come here and continue to live here. African Americans have our own culture but not all of us are the same so stereotyping is wrong either way. Honestly, we want to be connected to our African and Caribbean roots but get shunned when we try to learn or claim them. It's not our fault our history and culture was erased, forgotten, and beat out of us. At the same time non-american blacks seem to pick and choose which parts of the American culture they want to claim. African American people are accepting of other ethnicities and nationalities to our own detriment half the time. Especially people of color. We don't deserve the hate and judgment.
