The "btw, I use Arch" meme has been eclipsed by the "btw, I distro shame to feel superior" meme.
I'm not saying the original meme wasn't justified years ago; it certainly was ...but it's dead now! If you still go around shitting on people every time they mention Arch Linux in a post YOU HAVE BECOME THE INVERTED ZOMBIE CORPSE OF THAT ORIGINAL MEME!
Have some self awareness and find some fresh memes! And consider that you don't need to shit on people to feel good about your choices.
