Yeah, India is a secular state and not a communist state that bars one from following any religion, a PM, President, CM, or any other minister can have a religion also, and one generally take an oath in the name of the god/bhagwan/ishwar which are general terms and not religion specific, an atheist and non-believers or just anyone can also take an oath by saying "Solemnly affirm". Check the video again, the PM took an oath to abide by the CONSTITUTION OF INDIA, and nothing else. Now finish this before posting any slily reply.

And this was the oath PM took:
“I, Narendra Damodardas Modi, do swear in the name of God that I will bear true faith and allegiance to the Constitution of India as by law established, that I will uphold the sovereignty and integrity of India, that I will faithfully and conscientiously discharge my duties as Prime Minister for the Union and that I will do right to all manner of people in accordance with the Constitution and the law, without fear or favour, affection or ill-will.”
When it comes to secularism and respecting all religions, Bangladesh comes way behind India, in fact that country was originally formed on the basis of communalism and remained very communal till date. Bangladesh also has a state religion, Islam, right? India doesn't have a state religion even with 80%+ Hindu majority, that's secularism, something that you guys will never understand.
2050? Hindus will be extinct from Bangladesh by 2025, faster if BNP comes to power, they are already 7%-8% max.
A sharp drop from 30% at the time of partition.
Once you are done with rest of the Hindus, do come back to give us lecture about secularism.
