In answer to the topic question,
"YES" to racial discrimination (I am Black and I live in the US, in the South, need I say more?)
"YES" to gender discrimination (I am female)
"YES" to age discrimination (I am very small and supposedly look very young for my age, 36 yo)
"YES" to African American color discrimination as well (i.e., "light-skinned/dark-skinned" issue)
Most White people seem genuinely shocked that I speak regular English, have manners, that I have a husband, and that I am an considerably intelligent person. Throw in a lot of "unusual" tastes and interests, and sometimes I feel like I'm viewed as a freak, or an alien at most. A lot of White people only feel comfortable with trying to use "Black" slang, and high-fiving and trying to be a "homie", and talking about the latest rap/hip-hop songs/movies to a Black person. Most do not know how to address me or act towards me. Um, how about just as a regular person?!? Hey, that'd probably work!
The Turkish hair salon owners near my house have a habit of chatting up the White customers, asking about their health, laughing, talking about the weather--while I got only the barest, most perfunctory service. I no longer frequent their business because there have been several instances where they have rushed to wait on White customers who just walked in the door, while I (and other Black customers) had been waiting (and waiting, and waiting....) My mom let my sister and I take a craft class when we were 11-12, we were the only minority kids in the entire class, and the White teacher could barely hide her contempt for us, the freckly bitch. That was pretty miserable.
I had a White boss (a pharmacist) who would show her White customers all the OTC options on the shelves when they had medical questions, but to the Black ones she would always snap, "Well, I can show you what we have, but it's the cheapest--all the other items will probably be too expensive for you."
The Chinese waitresses at the restaurant we used to visit frequently left us stranded at our table for eternity, empty glasses and plates, while they laughed and joked with and basically ass-kissed the White customers. My husband still goes there, but I REFUSE to pay somebody to treat me like shit. And if I go into one more hair-supply shop and have the Asian cashier ask me if my hair is real...I swear to God.
A lot of people don't like when I use "big words." Some have said that "I don't always have to be so smart." Not "smart" as in flippant, but "smart" as in brainy. I never hear men being told something like this. I have to really assert myself sometimes to keep from being talked down to by people who think I'm a lot younger than I am.
Stuff like this doesn't happen every day by any means, but these are all incidences that I have had happen to me.
