Is it repulsive for a group of people of any faith to prey on those who are terminally ill and attempt to convert them to their religion?
No. They see someone who is in danger and want to save them. Thoughtful sentiment, often bad execution.
It's just people who hope others will find what they believe is the right path before death. They want them to experience the same things they experience. I would say it is a well intentioned and ultimately harmless gesture
Repulsive & rude.
I'm not sure I'd say repulsive, because I know there are people who genuinely feel obligated to do this because of their beliefs, & feel they are doing good. I would not have to want to deal with them myself, though.
I'd say so. I already think proselytizing, while it should be allowed, is somewhat offensive if done in certain ways, doing this would just be so manipulative its frankly bile producing.
