can you read
"Keep political ragebait to the politics stream the best you can. Normal political images are fine, just don't go overboard."
your images were NOT normal politics, but instead actual lies without proper evidence for the sole reason to ragebait.
"If you feel like posting 'I dislike [group] because of [xyz]', don't."
guess what rule you've been breaking
also it wasn't as bad as "kill garfieldfan" (except one commenter iirc, but one does not mean all). you're just overreacting on a proper ban
