My point is about understanding and analysis, not approval or rejection.

But if you mention the rejection angle, there I have a different fear: the general low sanity waterline means destroying other-wordly religion generates this-worldly ones and they are more dangerous. If people need to have wishful thinking, better put it into an other-world box and not apply it to the real world.

E.g. I think moderately religious people tend to be politically sane because they not need to invest their wishful thinking, hope, etc. into politics. They have a handy box called afterlife they can invest them into. Thus, they can afford to see politics in a sober way, not expecting much from it. They don't expect political saviors etc.
