Exactly!
“Guys” is gender exclusion.
“Nagging” is shaming women for asking someone to do what they committed to do.
“Pussy” is gender bias that women are weak.
It’s all bullshit.
For those who defend the use of any of these because we know what they mean, stop being a little shit. Just change! It’s not that hard.
I’ve always understood pussy (as in afraid, not the vagina meaning) to be related to cats?
I love the “I call everyone dude” shtick being responded with “So you fuck dudes?”. Shuts those type up pretty quickly.
I like thinking of it as cats.
I used to use dude a ton too. That seems to be a lot less negatively impactful for whatever reason.

It’s definitely a gender thing. Pussy=woman=coward. Even if you do accept the cat angle, cats are still seen as feminine pets and of course it’s slang for vaginas so you’re right back at the gender based insult.
You’ll get lying, two faced trolls trying to pretend they mean “pusillanimous” by it as the etymological origin but no one seriously believes them.
