Types in Verbal Combat

[xyz]

What if there aren't enough compelling facts at hand?

Then find more facts.

What if you're arguing a personal conviction?

I can't think of any activity that simulates banging your head against a wall more than arguing personal convictions with someone else.

What if the facts don't matter (i.e. arguing the logic behind something rather than the objective aspects of what it is)?

You still need facts for logic.
