All religions, consist of rules for how things should be.

That is not compatible with live and let live. That I reference the worst of them does not make the lesser ones innocent. Just lesser. Half bad is still bad. So is a quarter. Or any fraction.

Religion is informal law, which unlike actual law, is not up for a vote. And believers do get to vote, which can make their laws, our laws.

Trusting them to "live and let live" which in their frame of reference might doom others to some purgatory or other, isn't as valid an option as you make out. And I don't think anyone should have to make that internal moral compromise.

I don't subscribe to the idea that people shouldn't try to change how others live.

When does saving someone from drowning, become trying to force them to live like you do? Meddling for someone's own good, is not a bad thing.

Advocating for bicycle helmets is good. Why isn't saving people from hell?

The difference, is whether you meddle based on something that is real.

Some people do not believe helmets do anything. Should we not try to save them anyway?

Religions introduce a bunch of bullshit that has made saving people from themselves a shameful thing to attempt, just so that we can all semi-functionally co-exist.
