Do you know why I want to move to another planet?

Well it depends on how profound these ideas are. I'm a christian, but I have a jewish and athiest friend. We just don't talk about it. I respect their beliefs and they are nice people. If disagreeing beliefs get in the way of respecting the other person, then you should not be friends. Just because these people who befiriend you don't believe what you do doesn't mean you can't be friends. As long as they respect your ideas and don't make fun of them then I see no reason for their outreach to you is insulting.
