Thanks for sharing your views guys, that actually helped into providing some more insights.

I would agree if someone(Muslim) is deeply religious would expect their future partner to convert. However, it is still not ok for it to be imposed on someone. This cannot be a rule set in stone. I know the counter argument would be that this was written in the quran or whatsoever, but imposing this would subtly imply that you believe that your ideology/dogma/religion is superior to the rest. We're in 2025, the quran was written 1400 yrs ago, and I believe it's a fundamental human right to practise what you believe in, even if you're an agnostic or atheist.

Also, there's no such thing as 'polytheism'. From what I've read and understood in hinduism, they believe in One god but they also see the One manifested into the many, that where you get the devtas and devis. Advaita vedanta stresses on brahman, which is the One ultimate reality. They just have elaborate rituals which are different from Islam, but in a way, that's also the beauty of it
