I need to assert here, though, that this is NOT our intention, and I want to let you know that if you've had this experience, it's because someone cared enough about you to want you to have the joy he/she feels. Somebody cared enough to open up his/her heart and deepest feelings to you and wanted to let you in. If that offended you, and I can see how it might--it's hard to be confronted with something that could change your life--I'd like to help you see the other side of this equation--from the LDS point of view. Please note, however, that this is from one individual's perspective. Maybe other members would tell you otherwise, but I'd hope not....
We, as regular, normal, everyday members of the Church of Jesus Christ of Latter-day Saints are enthusiastic about what we've learned, felt, and come to understand about the purpose of life and the joy and perspective that our Savior has brought into our lives. When you get excited about something, you just want to share it, right? We are also aware, because at some point someone also shared these things with us, that it's a bit intimidating to share these feelings with others. How will they feel when I open up? What will they think? Will they be offended? Will I lose a friend?
It is a rare person, who can open up such things, be rejected, and then carry on in a normal way as if nothing happened. I wish this wasn't the case, but it is human nature. I would assert that most members of the LDS faith aren't that shallow to just drop someone because they didn't want to join the Church. It's just that rejection is tough to take. Again, that is not our motive in having friends. We want to have friends just like everybody else in or out of our own sphere of belief. If, after sharing his/her beliefs with you, that person dropped you as a friend, and therefore, further drove home the idea that he/she was only using you to convert you, I hope you can now understand what was going on.
If this has happened to you? Could you approach that LDS friend and talk about it? It might make you both feel better. Really, we members of the LDS church are just people, and some of us don't have as thick skin as you might believe. If you care about that person and want to be friends, why not say so and smooth things over?
I think, if you have an LDS friend, you should open up a dialog. Just a simple: why do you feel this way about this?
It'll probably freak your LDS friend out a bit. They'll probably be surprised just because we've come to accept the fact that talking about religion is taboo, but admit it, you've had questions. You've heard rumors. Don't you really want to know if they're true?
