Criticizing someones methods of activism is always kinda a joke to me. If you care, and think you have a better way to win people over - MAKE YOUR CASE - don’t tell others they’re doing it wrong and if they just said the right words you’d get on board and help.
The scientist making a religious argument, when they didn’t believe it, is just as easily dismissed as the scientist making the science argument. Turns out you need pastors and religious leaders and conservatives to make those arguments to conservatives. Why aren’t they? You tell me - i’d guess that a few do and the audience would rather hear other things - plus all the nice oil money goes to media that pitches climate denial messages
