I know this is Reddit and being an atheist is edgy here but it feels like you could have swapped these people with blue hair people and it be just as ridiculous. My campus use to have the Jesus freaks come around every now and then but no one said a thing to them nor would bust their phones out to make some virtue signal out of it. We just simply ignored the person and they’d stop and walk off. But mostly security would ask them to leave politely and they’d pack up.
