So there's not one Christian or Hindu officer in all of Starfleet?
The episode Data's Day takes place on Diwali. He says so in his log entry. Mind you in 400 years they may be celebrating the Hindu festival of lights without knowing what it means, just like Christmas nowadays.
"Don't try to live so wise. Don't cry 'cause you're so right.
Don't dry with fakes or fears, 'Cause you will hate yourself in the end."
