Pretty close to my definition - and not the dictionary's.Racism is discrimination based on race. Really nothing more to it.
Discrimination in thought as well as action.
Yes, but racism is simply a kind of bigotry or prejudice.Bigotry and Prejudice have their own definitions too
Word meanings aren't fixed.so we have to apply them correctly because if everyone said..."Eh I disagree with that definition" then what's the point in even having a dictionary? Instead of disagreeing with a definition, how about finding a more proper word that fits what you're thinking about?
