Well, the first one that got locked was a spin-off from the Covid thread, in which I was attempting to take Shark's conspiracy theory views into a different zone. I'm partly culpable for how things turned out because, rather than try to find peace in a debate setting, I'm more like a dog with a bone. I want to win. There are key moments in that thread where I could've backed off. I didn't. It turned ugly. It got locked. I'm not proud of how it turned out and I tried to promise myself that I'd just entirely ignore Shark so that I didn't get myself embroiled again in such a negative no-movement back and forth.
Then he was back on the Covid thread - and I tried to make my points circuitously without directly engaging - but that's difficult when one is being quoted. That one, I don't know how else it could've ended. He was determined that he had a right to make his points, he even posted an appeal that basically suggested a sort of ownership over the board, and he doesn't think his points are conspiracy theories - he just thinks he's right. So, despite being warned off on a few occasions, it was something clearly undroppable for him, it kept causing friction and it got locked. I like to think my existence didn't assist the lock in that case and that it was just inevitable.
My reflection about the whole thing is: it didn't go well, it caused negativity, it made a broadly well-liked boarder either duck for cover or get banned (?) and it makes discussing Covid a sort of taboo subject on the board. Personally, I need to avoid debate situations with that person, because it became clearly abusive. (My ego says I was abused more, but I have to allow that there was some rock-throwing from both sides.) Perhaps the key is this (for me): make points about the comic on the comic forum. Try to be like Facepuke, and post my own ideas, rather than respond to other peoples (especially if I diametrically oppose them).
