But I'm also assuming you know very little about debate tactics, is that correct? If so, the sentence I quoted seems to imply you seem to think you should be able to handle quite a wide range of things on the fly.

Nnnoo, it implies I thought I should be able to handle a wide range of events inside a public conversation (about religion) on the fly. This is a tiny slice of human endeavor.

I probably wouldn't say something similar nowadays, and I worry whether that might be due to decrease of energy rather than calibration of confidence.
