Aren't you both arguing for a culture of science? Of discussions dominated by experimental results and data driven decisions?

You can be as loud an asshat as you like, but if your opinions disagree with experimental results, tough.

Of course you can still be a loud asshat and right but that's a different class of problem.

The problem is that loud, wrong assholes tend to be be highly skilled at manipulative strategies e.g. Gish Gallop, etc. In fact, it's selected for. And you can't always counter disingenuous debate with honest debate - you just have to kick that person out of the room.
