So now I am delusional and spouting nonsense.

If you cannot argue against true facts,
throw slurs against the person’s character.
That unfair but often used tactic is so old it has an ancient name in a now dead language:
Ad Hominem

The reason for my original post was to help Moparts members make a bit of extra money.

I am willing to admit mistakes,
and have admitted to several here on Moparts.

As I have grown older my core philosophy has shifted to admitting mistakes quickly and changing course to correct them.

I make an infinite number of financial mistakes every day,
by not having invested yesterday in every investment that went up by today.

That used to be called a “sin of omission” but today is called a “Type II error”.
