I'm really starting to hate the term "normie" or the edgier variant, "normalfag". Why? Because literally everyone who is not on Facebook is using that term, including Reddit, Discord, some parts of YouTube or Twitter. It's meaningless.
I generally see it being referred to anyone outside of their views/hobbies, or who aren't part of whatever community they are in. That makes us all normies or normalfags from someone else's perspective. So you are basically saying that everyone who doesn't share the same niche hobby or world view as you, is "normal". Guess what, we all have niche interests.
Unless (almost) every aspect of your lifestyle is radically different that everyone else (that includes your job (or lack thereof), the food you eat, the media you consume, your political/social/economic views, etc), you are for the most part, "normal".
Mainly gaming/nerd instance for people who value free speech. Everyone is welcome.
