So if the politically correct term is "African-American", then why do we refer to February as "Black History Month"?
I want a Redhead History Month! Or would that be "Irish-American History Month"?
Both B.O. and cigarette smoke are stinky and make people sick. So why is the first taboo and the second one isn't?
People make faces at others with B.O., look down on them, make fun of them, move away from them, etc...The offender would not say a thing, and most likely, is embarrassed by it.
But if you do any of the above actions to a smoker, then you are not respecting their rights and they get in your face, not afraid to let you know it.
