I hold this position: {{my_position}}

My reasoning: {{my_reasoning}}

Steel-man the opposing view. Build the strongest possible case against my position — the case I'd have to defeat to remain confident. Then:
1. Identify which of my arguments is actually weakest
2. Identify the most uncomfortable counterpoint I should sit with
3. Tell me: what evidence would change my mind, and is that evidence easy or hard to find?

Don't soften it. Make me uncomfortable.
