Yup, poppagator, I can agree with that just fine. Well said, in fact.

I agree with "I especially don't care if anyone is put off by their misunderstanding of what I might be trying to say", though I would just say...

1. I do care when I'm misunderstood to the extent that I will try to re-examine what I wrote and try to assess if the understanding might have been the fault of my unclear writing. On the other hand...

2. There are those who (as I stated earlier) seem to be set on misunderstanding me -- even (and often) in spite of the fact that others are not misunderstanding what I've said. Those people I don't so much care that they misunderstand me, but I certainly change my tack when it comes to trying to communicate with them. I still favor politeness, but not even trying to communicate with some folks here seems to be the best, most polite tack to take.

I'm sure that many here have concluded the same toward me.
