It is an interesting idea, but respectfully I will say I'm not fully into it.
I like a good laugh, but depending on the topic the direction of commentary could potentially breed toxicity... like how the GamingCircleJerk subreddit acts sometimes.
If I were to call the shots, tasteful memes, politics being as political as you expect within that yeehive, complaining about how election coverage is nonstop and making fun of how annoying it is, is all fine and may not even require separate threads on a topic.
But considering that it is easy to cross a line into offensive territory when it comes to certain drama, topics or personalities, my view is the kind of no-holds-barred thread goes against the principles of Beehaw (feel free to disagree with me). However, I'm sure that kind of thread could fit well within other instances on Lemmy that follow a different philosphy, perhaps through a politicalmemes community.
