If you are sure that you are on the right side of an issue, prove to me that you didn't get there by blind luck. Show me the thought process. Show me why you're so convinced, if you can.
Show me that you recognize holes in your point of view. They're always there, even in 2+2=4. If you don't see them, that's a problem. (Is 2 apples plus 2 oranges 4 potatoes? No? What about 2 apples a thousand years ago and 2 apples today, is that 4 apples you can eat? Hm. What about 2 apples here and 2 apples in the backpack you left at work? Can you juggle 4 apples right now? Not exactly? Thank you, we have some provisos after all.) Show me that you are seriously considering complexities and other arguments that don't agree with your conclusion. Show me that you aren't above provisionally disagreeing with your position, or hearing a challenge to it in good faith.
To prove a thing, start by allowing it to be very much in doubt. Let any and every criticism fly. Invite tomatoes of criticism to be thrown. Throw some of the tomatoes at this thing yourself. Next, squeeze out most of the doubt by fair, transparent, reliable methods. Don't cheat by shutting out disagreement or shitting on people who don't fall in line. Let the best idea win in a free exchange; show that one idea wins naturally because it has the advantage of accuracy.
That I respect.
The rest? I respect the people, I respect that they have opinions, but I think the opinions are farts in a breeze.
