Using autism as an insult isn’t exactly colorful, it just shows you’ve never met and/or respected an autistic person.

Colorful would’ve been something like “fucknut idiots with donkey cum for brains”, or “shitbrained human equivalents of a week-old used tampon”, or “assfaces who would lose a spelling competition to a dead camel”, etc.

You could be a lot more creative, funny, and less offensive if your goal is colorful. If your goal is to regurgitate weak ass meme language from 4chan, keep equating people you don’t like with autism
