You're confusing logical/mathematic "truth" with philosophical/scientific "truth". While "politics should be based on scientific truth" is an opinion I have some sympathy for, even if it immediately falls apart under any scrutiny. "politics should be based on mathematical axiomatic truth" is a statement so laughable I can only imagine you forgot the context we were talking about.

P.S. I'm not confusing anything and not forgetting any context, and then I get slammed with an absurd strawman, "politics should be based on mathematical axiomatic truth"--not remotely anything I said. Gawd but some people are rude.

The fact remains that absolute truth exists ... "delusional" seems to have no idea what the word "truth" even means.
