I’m not talking about like… brigading or conversion stuff. To use an example from my own life, I (ironically) teach at a Catholic university and, on occasion, a student who is questioning their faith will bring it up to me because it tends to come up that I’m atheist. At that point, it’s not a matter of forcing anything on people, it’s a matter of giving support to someone who is going to have a really hard time dealing with their family, friends, and school. Online communities are great for that.
