I've had some people who were persistent, who will follow me and keep talking, much like a strange dog might follow you and keep barking. Like with dogs, if you keep walking away they do eventually give up.

I have seen videos online though were dome people were literally tortured and they describe (recounted) how they had electrodes attached to their genitals to give electric shocks. Of course those videos were about trying to cure the "gay" out of people, usually with the consent of parents (if under 18), bu tin some instances, adults were literally kidnapped and subjected to torture to try to change them.

When I was in high school, I got up and walked out of a church because the preacher was getting weird and crazy. As I was walking out, he told the congregants to grab me before I could leave. That scared me so bad that I ran out as fast as I could.

I've never heard of conversion by force in modern times. It seems unlikely that coercion or threat would accomplish just the opposite.

All the time. I used to just mind my own business. But then at the dawn of the civilian internet, I noticed that any Jewish group (I'm culturally Jewish) would quickly be invaded by rabid evangelicals. So I started fighting back. I once caused the entire religion section of Taboo Groups to be deleted. And now, by the time we have Facebook, my sparring is typically challenging these people to actually perform experiments rather than just saying that one particular evolutionary theory or another is wrong, or that there has to be a prime cause (ha!) or whatever. And I uniformly get literally consigned to hell when they run out f counter-arguments.
