First of all, this copypasta has never been said by anyone at the FSF or from the GNU project. People falsly attribute it to rms even though he has already made his thoughts clear on the matter. It’s just misinformation and a bastardized take on the naming discussion.

I mean most Linux systems with a few exceptions (looking at you Alpine) use gnu software in them

It’s not “GNU software in a linux system”, again, GNU is the name of the operating system. GNU packages were developed for that operating system. Alpine is not GNU, it is a NonGNU/Busybox + Linux operating system mainly targeted for embedded devices. Linux is not a GNU package, but was liberated by Torvalds to be included in the GNU operating system which we now refer to completely as GNU/Linux.

and it is a somewhat fair argument to say that a kernel isn’t an entire operating system and other factors should be considered

Such as the freedom of software writers and computer users. Calling the operating system “Linux” is taking away (even if not by intent) the very principle of freedom of the GNU operating system. It isn’t “somewhat fair”, far too many people who use Free software do not understand it entirely and thus are vulnerable to closing their hands from further liberation.

Also why the quotation marks? It is a Linux joke, and if you don’t like our humor than you can just kinda… Ignore it?

If “Linux humor” is repeating the same 5 or so jokes and endless banter about the same topics then it isn’t productive. Especially if that humor is just spreading misinformation in service of a cheap gag made by others. I’m just calling it out when I see it because I’m done giving a lot of yall the benefit of the doubt anymore.
