People who claim "guys" is gender neutral would most often only count men when asked the question "How many guys did you sleep with in your life?"
Until I find a single person who immediately thinks of people of any gender at that question, I will not fall for the internalized misogyny of "'guys' is gender neutral" meme. (Same with "dudes" and all the other ones I've seen over the years. I've even seen someone say "bro" is gender neutral.)
And then you bring up defederation and/or how instances can die at any time and you lose them again...
At least that's how it usually goes for me and trying to advertise Lemmy. Not really a fan of "microblogging" to begin with no matter the platform.
