Why use this sort of language?

> What I said was true, it isn't FDIC insured.

But it is a banal truth, because they are simply insured by a different agency.

> I don't know anything about NCUA and I don't care to learn

So you were motivated by apathy and content in ignorance, rather than trying to scare people, with your language. Still a bad choice because it shows that you're not seriously trying to engage in a discussion and learn about a subject.
