I'm reasonably sure the GP is referring to the fact that there are explicitly political aspects to Islam (wanting an Islamic state) that don't exist in other religions.

I'm not sure I agree though, as Judaism now has a state and Christianity had one and lost it.

I mentioned "remaining" as the explicit political aspects are in all religions, it's just that as we came to modernity states became secular, and only Islam remains with that element still largely in tact.

I did mention the Jewish state as well, but imo, since it is based partly on ethnicity even for open non-believers, it's kind of a mix between a secular and a religious state

it means danger to the non-believer

Yes, that is pretty much what I mean. But the idea of a unified Muslim state is also still pretty alive in the world. In a way it's not in other religions (Judaism is an interesting edge case, imo)
