"I have something of a reputation of being a woke scold . . ."
A reputation that, based on this article, is deserved.
1. Fat positivity is a self-fulfilling death wish. No amount of body positivity or fat acceptance will make obesity healthy.
2. "Protected Black words," isn't a thing. Nor is "microaggressions," for that matter. The time was when it was considered a sign of strength and character of overlook the petty slights that each and every one of us is subjected to. Nowadays, it's considered laudable to look for and be offended by slightest offense, real or imagined, and howl with indignation and sob profusely.
3. No, not all White people are racist. That belief, in and of itself, is racist.
The rest of your points are equally shoddy. But congratulations on your wokeness. I'm sure you scored brownie points with the right people.
You might be happier, however, if you tried to look past trivial grievances instead of justification to be offended.
