I’d say racism. I was taught not to trust or be friends with African Americans. My parents went so far as to take me out of the city to be raised on a farm. I remember the first time an African American talked to me I was scared. I had to teach myself that bigotry and racism is wrong. Now I can proudly say I’ve been friends with and dated every shade of the skin tone rainbow. And I’m raising my children to not see color as a negative but just as a trait we all have. If that makes sense.
