It's a really hard balance to strike and very few ever agree on were that should be.
Places like FB I think are too sanitized (and also really don't even want to be places for any real discussion)
The old DCC (and the old YouTube) were way to far to the 'anything goes' side. Thus...in that scenario the scum rises to the top.
Reddit and the like I usually just lurk on but the are some really in the middle, but can quickly go south into the bad territory.
DGN is , intentionally leaning toward the safer side, but we should be able to make unpopular options and not get attacked for it.
The hard part comes when an opinion is so offensive that it triggers a series of even more offensive statements, which can mean the 'just an opinion' is more than that, pragmaticly. (Hasn't happened here in a long time) Or a long, long history of always being semi rude, but not actually directly attacking anyone, it gets tangled. But we try.
The social observations about the makeup of the internet were interesting.... Typing this on my phone so I have to stop before my fingers fall off. Lol
