The internet has a way of taking things that are used sarcastically and removing every bit of irony. The Flat Earth Society, PCMR, and The Donald subreddit all started out as making fun of the people that are now 100% unironically part of very thriving (and toxic to differing levels) communities.
I think that will almost certainly happen to the word normie, if it hasn’t already.
To be fair, I did say “well established anecdote” and not “well established fact”.
