Yes, they're crazy. It's when I see stuff like that when I understand why some Muslims nullify them. Not that I agree. I simply consider them misbelievers. There may be some shias that do claim Ali PBUH should've been prophet etx etc. Those people obviously are kaafirs but to generalise them all is just wrong. And I just noticed my phone changed the words lol. It's clled ashura and the battle of karbala
