>>95972596 (OP)In a well written story? Yes, worshippers of evil Gods won't be tolerated. Faerun and D&D as conceived and written for most of its existence was not a grey and gray morality setting. Good and Evil are objective tangible things. The IRL equivalent question would be "Would you tolerate a store that sells Cheese Pizza media and is run and frequented by people who openly admit to wanting to SA children and there are a few that have done so"? No, such an establishment would create an intense revulsion in whatever community it tried to establish itself in and even if the local laws allowed it vigilantism would rapidly take care of it.
Of course D&D nowadays is run by a group of likely pdfiles, so kultmarx proselytizing and neolib subversive tactics to confuse, brainrot, and mkultra weak willed normies is the name of the game and in post 2014 D&D settings I doubt anyone would give a fuck if someone was openly worshipping Shar on the street and sacrificing people to her (as long as it couldn't be framed as a racist thing, since racism is le only ebil thing left nowadays).
