I thought I was laying on the sarcasm pretty thick. But I guess it’s harder and harder to tell these days!

I took as beyond sarcasm, just a simple explanation of how they manage to keep going written in the first person. From my perspective it is incredible anybody could misunderstand.

That's how I took it too, and didn't realize someone might read it otherwise, but I can see how it could be misunderstood if someone isn't paying as much attention.

There is no tone of voice in writing. This is part of the problem with written social media. Some writers will say "only an idiot would believe what I wrote", showing themselves to be adversarial in their communications. I don't think that's you in this case.

Dry humor wouldn't work if tone was necessary. Tone is a bit on the nose.

It was very thick, IMO.
