Venting is not debate. I don’t agree that Lemmy needs to be the place for venting, at least not in this community. Maybe in one designed for that. Debate for sure, but this isn’t debate, it’s a slapfight, as you noted.

Of course, you are welcome to moderate your communities as you see fit, but when I see users refusing to learn from previous rule enforcement, I tend to reach for the ban instead of spending more time and effort reviewing their negative contributions, as it’s harmful to the community.
