I think you are onto something there. It isn't religion, atheism, quitting smoking, or whatever someone is passionate about that is bad or offensive. It's people who are so passionate about something that they aren't able to step back and allow for others who want to make their own choices. It doesn't mean that what they offer doesn't have merit, it's just that nobody wants anything forced on them. We need to be able to make our own choices. Agency and choice, by the way, are concepts supported by religion. Maybe it depends on the religion, but they are crucial to mine.
