"read the sidebar" is not a great solution when I'm using Connect for Lemmy from my phone, and there is no sidebar.
I suppose you're right about people knowing The Onion is fake because of its popularity. But saying people are losing their sense of edgy satire might be a sign of how crazy things are these days. Like with what is happening in the world right now, a headline and article like this is absolutely plausable. Ice agent kills Good. Nintendo sues Bowser for piracy... Half of the real shit happening out there headlines like an onion article. There's a whole "NotTheOnion" community based on this.
Like I said, I like the creativity. I read the whole article and enjoyed it. But I hate the idea that I need to fact check every little thing that I read, especially in a community that prides themselves on separating from mainstream news media garbage.
