More seriously, I've never been in a situation where I've needed to avoid proselytizers, because the default assumption in my country is that you belong to one of two religions (Islam or Christianity), and explicitly proselytizing on the street or in some other public space could get you in legal trouble pretty quickly (and social trouble as well, if you're a non-Muslim even daring to think of convincing a Muslim to leave their religion; that could easily be physically unsafe).
I've had a few people preach to me after finding out that I'm a secularist, but all of them stopped when I indicated disinterest in the conversation. I usually tell people in such situations that I appreciate their concern but that I've spent years thinking about various positions and that I'm comfortable with my current one.
I really do appreciate their concern if they're coming from a place of sincere intentions, because I know exactly how it feels to worry about someone's perceived fate of eternal suffering in Hell. When I had that belief, I sometimes did the same thing to try to "save" people I cared about from ending up in eternal anguish. How could I not try if I had that belief, really? It makes perfect sense within the context of that worldview. I would actually find it more strange if someone had that belief but did not try at all to "save" someone they cared about.
