Expressions I’ve tried to stop using, and why:
"guys," in reference to a large heterogenous group of humans. Not everyone is a guy, and guy is *not* gender neutral no matter how much guys want it to be. I've been using “y'all,” "folks,” “they," and "them” instead.
"American," in reference to a USA-only subject. The US isn't the only nation state in the Americas, dammit. We're not even the biggest one. I've been trying to explicitly use "US" or “US-ian" where applicable instead.
How about you?
