The establishment and Free Exercise clause forbids the state from allowing itself to support any religion. The free exercise clause prohibits it from denying free exercise of religion to anyone.
IMO this action does not at all abridge the religious freedom of a christian. It simply dissuades a proselytising individual from abridging the freedom or religion of another.
Pretty sure an order banning proselytization would stand supreme court scrutiny.
“It simply dissuades a proselytising individual from abridging the freedom or religion of another.”
If a Jehovah’s Witness comes to your door, how does his presence abridge your freedom or religion?
I spent 25 years in the US Air force. There were no mandatory religious meetings. In 25 years, no one ever ordered me to believe. There was a lot of peer pressure at times to go bar hopping, perhaps, but never any to go to church.
