doPe! I love learning about other languages and cultures. I definitely picture a horse when someone says Arabian. My grandmother used to say people were Arabians and orientals and I was like those are horses and rugs, not people!
With that being said, I think it has been a little tricky for me to figure out how to refer to people who have ancestral roots in (The Middle East? Persia? Places Alexander the Great colonized?).
I can finally mostly differentiate between Arabic and Urdu when I hear it, but it took me a long time, and only because a guy used to date said Black people don't know the difference between Palestinians and Pakistanis and... I simply could not let him be right.
Language is complex, and sometimes I'm guilty of staying silent rather than taking the chance I might offend someone. Thanks for dropping some knowledge on us.
