Is Kolkata and West Bengal Safe for Muslims? Job Opportunities, Cost of Living, and Lifestyle Insights Needed

One of my friends, who was born and raised in Chennai, is considering relocating to Kolkata with his wife and 5-year-old child. He comes from a Muslim family. Given that Tamil Nadu generally has less communal tension, I am curious to know if Kolkata and West Bengal are similarly safe for Muslims. He works in the lecturing field—how are the job prospects in this sector? I’d also appreciate insights on the entertainment options, food scene, and cost of living in Kolkata. Any advice or useful suggestions would be greatly appreciated!
