There's nothing wrong with this (in fact, it's correct), but the challenge is to prevent our hatred of the institution from spilling over into hatred of its followers. It's a known fact that antagonizing cult members only alienates them more, driving them deeper into the security of their group. Our job is to treat them with respect while simultaneously rejecting their views, beliefs, and attacks on personal freedom wholesale. We must also try to recognize when a belief crosses over from being benignly silly (most Christian denominations) into being actively harmful to its members and civilized society as a whole (Evangelical Christianity).
While I don’t believe in God, this is still the right answer. God as a character or real thing must go to the grave, metaphorically or otherwise. If the Aztec and Norse gods for the most part along with Typhon and Pan can be killed, along with the waning of their for the most part hostile theology, so too can the egotistical storm God of the Sinai Desert.
