Great, then show me evidence of that. All you've provided so far is a claim, backed up by nothing, that the French invented the word 30 years after it was first used.

And yes, I did follow the link. From the usage notes on that page:

"Some speakers use the term racism loosely to refer to prejudice or discrimination based not upon race but upon other factors; this is nonstandard."

Again, racism isn't simply about "others". It's about race. "Others" include religion and gender and nationality. When the Hutu massacred the Tutsi in Rwanda, that wasn't racism. It was classism and tribalism. I'm not saying you're arrogant, I'm saying that you're using this word incorrectly. The link you sent me says this too. Why is this so hard for you to accept?

What you're talking about with the black people you grew up around is recognising bigotry of one form in bigotry of other forms. I think this is perfectly valid. I understand bigotry against women and gay people and all kinds of other groups, even though I'm not a member of them, because I have insight into the bigotry of racism. We use different words to describe them though, because that's how language works.

Why do you feel that the suffering of your ancestors is somehow undermined if we don't use this particular word to describe it?? I'm genuinely baffled by this.
