I’m an atheist and a Satanist. I agree that these people are, by the measure of what the Jesus Christ of the Christian Bible is claimed to have said, hypocrites. At best. And yes, Jesus said that you should pray in private, and that people who pray in public so that they can be seen to pray have already received their reward. (Matthew 6:5 - “And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward.”)

But it’s still a foundational civil right.
