I have addressed all of these points before. Are you asking me to define racism? How can one accurately define such a term? It's a base emotion, like hate, or love - you know it when you see it but trying to use a form of words to wrap it in a neat envelope is probably insufficient.
We could use the dictionary, as you did earlier, but we should note that
Ultimately, the debate is then reduced to the definitions of words. I am not interested in going there; how dull.
If your instinct in these kinds of debates is to call people racist, or insinuate that people who say "hang on that's a bit harsh" are not concerned about racism, then you should be prepared for people to take you up on that.
I maintain that jumping in with a first and second contribution calling someone - quite directly - a racist, was unfair, unproductive, and unwarranted. It is very clear that you had no interest in explaining your own concept of racism until pushed into it.
We'll leave it to others, I guess, and I'm quite happy for them to judge whether they think I'm a racist, a racism enabler, "someone who attacks anti-racists" or perhaps none of these. I have made more than enough posts on this topic and I don't feel I need to defend myself from your ridiculous assertions.
