Anyone who denigrates the religious beliefs of another must have none of his own.
Chastising criticizing attacking insulting denigrating religious beliefs for what purpose? Calling in to question the sincerity of those beliefs is done by those who aren't sincere don't believe and have no clue. They do it VERY LOUDLY AND PROUDLY repeatedly overly muchly consistently endlessly.
Do you buy that schtick and believe the snake oil salesmouth who tries to sell you on it? What if he attacks YOU and YOUR religious beliefs similarly? Would you quietly accept the venom, roll over whimpering and agree with him or would you be insulted incensed disgusted? I'm betting you'd roll over whimpering and not disagree.
This is the way world works today. Like it a lot or not at all?
