I don't see any casuals doing anything beyond being keyboard warriors
While correct, some of that is because they generally tend to be less active online in places like Reddit (I've personally run into the most militant casual players on Untap while seeing extremely few militant competitive players; the closest to the latter I've seen are simply extremely insistent commanders like Atraxa and Golos are just as competitive as standard cEDH decks and refuse to listen to contrary opinions, which while weird probably isn't a huge issue.), even if sometimes active at the LGS level or in other places. The occasional stories on Reddit coming from infrequent contributors to MTG subreddits who simply went to the first place they could think of indicate there is a not insignificant group of players with hostile views toward what would even be judged by many here as fair-game casual play, even if they largely keep to themselves. We just don't hear about them as much because they keep their complaints to themselves or heckling players who stumble across them. The Reddit thread I linked has many stories of MTGO EDH, which apparently is quite toxic, although I haven't played on MTGO myself. Perhaps they are the trolls doing their things in their troll cave, occasionally eating passersby who stumble into their dens. Their issues are general toxicity rather than anything wrong with EDH specifically, as the same phenomenon can be encountered with other formats too. "Militant casual" players that are a bit too outspoken or deviant in their views are also more likely to err on the side of the RC, as often the issue is that their applications of Rule 0 create an unfun environment for anyone who happens to think differently; obviously the RC isn't responsible for these people, but many of them view players playing in what they see as a competitive or unfun way with the same animus the annoying cEDH people view the RC. It's not hard to find toxic MTG players.
Exactly. I don't think the compass needle has shifted toward those infrequent subjects of Reddit venting (or on here too when we complain about playing online) because the major issue has been the dynamic between cEDH and "normal" EDH. Perhaps that scale should have a new term added, something like hEDH for hyper-casual EDH, characterized not only by the level of play but by the aggressive avoidance of "unfun" elements to the extent that they create toxicity? These are the sorts that play on MTGO and quit games seemingly arbitrarily whenever their idea of fun is violated, or that aggressively house-rule to the point that outsiders feel excluded. Just because this group is seemingly more silent and hence not the target of such furious debate doesn't mean that they are insignificant; I imagine they form a good chunk of the silent majority that's often described when discussing the impact of bans and rules.I also find them being called out at the same time. I haven't been finding that to be the same case with the cEDH extreme lately.
