Problem with number 7 is that with unrestrited rights to proselytising, you have the potential to exploit those who are most vulnerable.
I mean, I used to wonder why it seemed that Jehovas Witnesses and assorted other cults' temples seemed to congregate around universities. And then I realised, where else do you have a populiation of potentially isolated/lonely/homesick/anxious young people ripe for the picking?
it's not an especially comforting thought tbh
But non-"unrestricted" proselytization violates the First Amendment and presumably any other Western democracy's equivalent. Also not sure how to limit it in even ignoring that. Should it be illegal to invite a friend to go to church with you?
BTW you also explained why hipster Christianity grows so fast with its demographic.
