Mohammed originally wanted jews and christians to come on board, but the jews did not like him as a prophet because … he was not a jew! so I bet Mohammed was real angry at that.
Similarly Jesus wouldn’t have been going around telling everyone to be Christians. He was telling jews to be better, different, and stop abusing some of their own laws like making profits at the temples.
All religions have some questionable writings in them, ideas and behaviours that are not good in my opinion. Pick any religion and focus on them and you got yourself some bad people.
All religions have some really good things, good ideas about ways to behave and treat others and have a good life. Pick any religion and focus on those things, and you get some good people.
It’d be nice if someone rewrote these taking out all the bad stuff. Or at least, if people didn’t preach them, focus on the bad stuff, and adding their own interpretations based on hate. And killing people who disagree.
