Incorrect. In ordinary usage, “racism” means prejudice based on race. There are efforts by some to muddy its meaning, to encompass both racial prejudice and “disproportionate effect,” but that’s not the common usage.
Thank you. For some reason I've never been able to explain it so succinctly when two people I respect get into an obviously semantic argument around something being or not being racist and then getting lost in the weeds of the intentions of the long dead.
Sounds like you are referring to a connotative value which is common to a subculture of English speakers. I learned to use the dictionary definition from sociology 101.
