I used to live in a place that had a big problem with people of a certain religion going around and trying to convert people at all hours of the day. I'm talking 7am, 10pm, and so on. You could be leaving for work and walking to your car and they'd try to get between you and your vehicle while telling you about how wonderful the religion they represent is. There were women who would ask politely to use your phone for a moment, and once they were done, would take their time leaving so they could guide the conversation towards converting you. I can see how it sounds like a good idea to someone of that religion if
they had absolutely no empathy or regard for other people, but other than that all it seems good for is swearing people off what they're trying to sell.
When it's happened to me and I'm aware they don't take no for an answer, I would pretend I didn't speak any recognisable human language. They'd give me a flier and leave quickly. Contacting their church was useless, since it was the church that was encouraging it all. Then once my husband (who is not white) answered the door and they fled and never returned
Where I live now, it is thankfully illegal to go around trying to convert people like that. You can have a temple for your religion and make information about it publicly available, but you ahve to wait for them to come to you. You can't go telling people who didn't ask, let alone have organised conversion door knocking going on. For the very first time in my life, I can walk around or even into a place of worship and not feel afraid of being assaulted by underhanded idiots trying to 'save' me.
