I'm sorry jdc but while I see the point you're trying to make several of your substitutions are not even vaguely like-for-like: "I sit away from black customers" and "I sit away from non-smoking sections" for example: a courtesy to others being turned into a statement of aversion.

I'm not going to delete any comments, because I don't believe that helps, but I'd appreciate it if you could apologise for upsetting saffie - at least make it clear you don't believe she's a racist or similarly bad.

We've all seen people use nazism as an analogy in the same way you've just used racism, and I doubt you think that's appropriate. Or do you really think smoking is as unpleasant as racism?
