if you call everyone dude and a transfem person gets mad about it, don't get defensive. just say like "sorry, i won't do it again" and don't argue "actually it's gender neutral" or "i call everyone dude". even if you do, i guarantee she's heard that argument from someone who very much does not call people they see as women dude. i certainly have
same goes double for the word guy.
"yo", " hey", "the person", " mate", "buddy", " pal"
going to be honest, though - directing any of these or even "dude"/"my guy" at the person you're talking to is fairly accusatory. you were pointed to the plural forms because they soften the blow.
Really? I thought "how are you doing, buddy?" Was more endearing than without the buddy part. Also didn't know mate, buddy and pal were neutral, thanks!
I was thinking mainly about leading a sentence with them:
"mate, what's going on?"
expresses more concern than
"what's going on, mate?"
I can see what you mean. Thanks again!
