Some people just don't care if their religion is true or stupid, or if their policies are right or wrong, or even if their policies are just plain cruel. They just don't care if their religion's policies cause suffering and death. They just don't care if their religious leaders lie or what they do with donated money. They don't care if abuse victims are treated like sinners and abusers are protected by the silence of the elders. They just don't care. They're happy, so that makes it all ok.
I couldn't have said it better myself, honestly. You've distilled it down to its very essence in a few short sentences. Bravo.
