I would like that, actually.
IRS in churches: make sure they're doing what they say they are and make it mandatory that they devote a percentage of their funds to helping their community if they want to be exempt.
Religion in schools: World religions and philosophy. Have the kids learn about their own religion and the religion of others (or lack thereof) to foster greater understanding and acceptance.
Prayer in school: Time set aside, every day, for meditation, contemplation, mindfulness activities - preferably in nature or at least a nice garden. No specific god, gods, or practice required, just the time and space to chill, be at peace, or think good thoughts.
Let's have all of that, actually.
Who am I kidding though? People suck and would 💯 find a way to eff it up. 😞
