Making people laugh and triggering people are quite different motives
I’m happy that we can now at least forget about inferring the education levels of people.
What I do see though is the usage of the language by native speakers. I pretty much never see a woman addressing a group of women by the "gender-neutral" "guys". I often see males addressing a group of males by "guys". Even this mismatch tells me enough about how neutral this term is among the people I see.
I also see males addressing a mixed group by "guys". When called out, they say "oh, but I didn’t mean it like that, many other people do that, the word is now neutral". Which might be even true despite the evidence mentioned above, but it still carries an awful lot of resemblance to other excuses about non-neutral language and behavior. I guess you can see why some people see this as an excuse.
I come from a country which in the last century had probably the best women’s rights in the whole world. And it still struggles with appropriate usage of neutral-gendered and "female"-gendered forms of words, and the excuses are all the same.
Do you include in this group everyone with English as a foreign language like me?
Sure, and this only strengthens the point of the counter question
I guess having to explain this is a good enough reason to avoid this allegedly gender-neutral word in gender-neutral contexts
The classical answer to a male is: do you sleep with guys?
And is just happened to be like this because of email. https://www.rfc-editor.org/rfc/rfc805.txt:
The major conclusion reached at the meeting is to extend the "username@hostname" mailbox format to "[email protected]", where the domain itself can be further structured.
