Why are online Christians so insufferable?

So haughty and self-righteous in their hate, bend to their will or you're the bad guy, call them out on their hypocrisy and give them a taste of their own medicine and you're the bad guy. They make a stupid rant ending with "Christ is King!" Like ok, you're still an asswipe. Hiding behind Christ to push a narrative, usually a political one. I question how religious these people truly are.
