US may not be officially Christian but it is predominantly Christian. You like it or not, facts don't care about your feelings. US has the most numbers of Christians in the world too.

My problem isn't with other religions, nor do I want them to be Christians. I'm just saying that people should know the faith that most Americans believe in is all. That's not a bad thing. That's how it should be. Whatever country you're living in, you should know the religion and culture of it. It's not limited to the states. 🤷‍♂️
