Question on being racist toward white people? Opinions?

Ok so, I know that alot of the time there has been racism from white people toward other ethnicities. But sometimes it bothers me that people dont bring up the fact that other races can be racist toward white people. Im mixed (puerto rican and black but mostly puerto rican) and i have had my fair share of run ins with racist white people..but ive also been treated bad by black people and spanish people alike due to the color of my skin or what its in my blood. I see a lot of shows that encourage people of different ethnicities to feel beautiful and I think that is wonderful. But I cant help but see how bad they put white people in the light. Like my moms best friend is white. When she went to a primarily black area, they treated her like crap for NO reason. Sometimes they say white women have skinny lips, pointed noses, too skinny, etc. I dont know..i dont think its fair. Not all white people are bad people, just like not all black people are bad, spanish, asian, middle eastern etc. I think all races are beautiful in their own way. Sometimes I see white people on t.v. get badly treated by other races..and its like maybe they didnt do anything wrong. Maybe they want to do what u wanna do to. My thing is..if u dont wanna be judged, dont judge others. Treat people the way you wanna be treated no matter what race. Has anyone else besides me noticed this? God Bless
