As long as people aren't doing it obnoxiously, it's fine to share your beliefs with people and hope they will be interested. I mean, my religion is something that makes me incredibly happy so of course I'm going to want to share it with people I love. It's like sharing sunshine. But, if you're super obnoxious about it and tell people they're going to hell because they disagree and you can't have a conversation without bringing up religion, that's ridiculous.
I just think that this goes two ways. "Please don't try to convert me" and "Don't be a jerk when all I want to do is share the most important thing in my life with you."
Those are my thoughts
