It's also so tiresome. I've seen people have started using other terms in place of retard in other places on the 'net.
On Twitch (the streaming site), for example, they use pepega (which is a depiction of a distorted and exaggerated version of the Pepe the Frog).
Or more recently, they've starting calling things and people "highly regarded" instead of "totally retarded".
The Euphemism Treadmill is real.
Some of us are better on the digital front, and some of us are better face to face. Without the digital sleuthing, we would have little to no info, and without wonderful people like you to disseminate that info face to face, we wouldn't win the hearts and minds of the public!
Keep being you!
It's fitting, given how cats are basically the unofficial mascots of imageboard culture. E.g. "it's Caturday, post cats", cats as meme subjects, even the villain of the old videogame Wing Commander is named "CATS" (the origin of the "all your base are belong to us" meme), and so on.
Funny thing about laws, they stop being laws once enough people decide they're bullshit.
