I think if you are a TRUE follower of Christ, you wouldn't judge him based solely on his religious beliefs. Kind of cheapens Christianity and loving one another, loving the sinner and hating the sin, etc. My sister was deeply into following Christ, so I know the experience of someone judging when Christ himself said (Matthew 7:1) "Judge not lest you be judged."
We must judge (or discern) as Christians between right and wrong, good and bad. But we must not have a judgmental attitude. Anyone who sizes others up with a swagger of superiority is not behaving in a Christ-like way.
But you do you.....
I have to admit that I'm David has the closest view to my own point of view (which is neither right nor wrong, it's just my view)...
Nowadays, in my old age (50's) I'm more of the belief that everything is destined by God, good and bad... and if God should allow that a person of different beliefs contacts me, who am I to go against it?...
If its good, like finding a soul mate then I should look deeper than normal at it or ask my learned scholars where the right path is...
If its bad, like getting ripped off/scammed then I look into myself to analyse what I could have done wrong, that God is punishing me...
Also I think you are doing the right thing by bouncing it off the community, because you can read everyone's views and at the end of it, use the most powerful computer on the planet (the human brain) to make a decision based on all the facts, or even pray to God to show you the right path...
Finally I think it's only fair to add that if the op respects your beliefs and doesn't ask you to change, then surely the op is also a believer in some respects and may revert back to the religion they were born into, since most people are born into a religion and because of not practicing it they change their beliefs-status to atheist or something else...
