Worshiping idols by anyone, Hindu, Martian, Klingon is offensive to Muslims, Christians and Jews.
BUT it is still tolerated.
There are however some countries, which have embedded religion into their constitution and might even ban it.
But according to my knowledge in no secular country with majority Muslims, Christians, Jews the worship of Idols by Hindus is banned.
The same way we would expect that a country like India, which "proudly" calls itself a secular country, should not enforce the majority religion's ideas on minorities. At least not as long as she wants to call her secular.
