I, for one, approach every discussion online with cautious open-mindedness. My time is limited. It doesn't take much for me to want to direct my energies elsewhere.

You can call it virtue-signalling, you can say that asking questions is forbidden, I can say that I'm under no obligation to talk to you or anyone.

And I've learned, through my own experience, that there's a familiar form of discussion that I am not interested in having; the person I responded to hit that form and showed me my energy is better spent elsewhere.

You can talk to them all you want. It's a big internet. I don't have to, and I won't.
