Actually niche online communities aren’t weird. Just because a topic isn’t repeated over and over again on big media doesn’t mean it’s weird. Big media doesn’t dictate what is normal.
What's wrong with "weird"? It means: fateful, uncanny, magical. It's never properly been an insult, and those who misbelieve otherwise and deploy it in a pejorative fashion accidentally do that which they so label a favor by avoiding it - nothing ruins a small, special space like an influx of people who neither understand nor care what makes it special.
