I think we're now almost fully aligned on this segment of the topic. :)
My observations of racism and its use were based on the definition in the dictionary, which I think places it at a higher standard than its more common and ever devolving usage. There are other terms for all of the other instances that often are cited but then lumped together. I think they should be used instead.
I agree with your comments about context and consistency. By our thoughts, words and actions we tell the story of our true selves.
I am in agreement that hate or discrimination based solely on race or ethnicity is bad (hate being bad in general, while discrimination still depends on context, like race).
Most of what seems to constitute racism has more to do with differences in opinion, politics, culture, goals, interests, values, behaviors and real or perceived social and economic injustices. There's probably more, but as I said, I think we're already agreeing on principle here, and that's cool. :)
