A rational argument is an argument that follows some sort of logical thought process, it has nothing to do with whether the conclusion is correct or not.
This is a rational argument:
- Premise 1: The Earth is a planet.
- Premise 2: The Earth is flat.
- Premise 3: All flat planets have edges.
- Conclusion: The Earth has edges.
Premise 2 is false, and premise 3 is unknown, so the conclusion is false, but it follows a logical thought process and isn’t nonsense.
This is nonsense and irrational:
- Premise 1: Apples are round.
- Premise 2: Pyramids exist.
- Premise 3: Unicorns have horns.
- Conclusion: Aliens!
There is no discernible logic or rational thought process. It is just apparently random statements with no connection.

Again, since we can’t even agree on commonly accepted definitions for basic concepts, we just aren’t going to be able to have any kind of productive conversation.
Good day.
