Everyone is entitled to an opinion of what they feel or believe in - be it a deity or something else.
Belief in the paranormal, living with it or experiencing it for the first time ... the confounds and structures of a particular religious belief and what building you go to (or don't) to practice that belief is really not that different other than the literal topic.
The problem that seems to be in the way many times is the inability for folks to agree to disagree on a subject. If someone does not believe just as you do, does that make them less of a person or wrong in what they're saying? No, it is just a different belief.
As in life you will find the same in with the other side - differences in experiences, beliefs on how to handle a situation, etc.
If you know someone doesn't believe in something or doesn't want to broach a particular subject, you must decide - take it for what its worth and move on and accept and respect their beliefs and wishes or try to shove it down their throats and insist to them that this is the only way. In all honesty, it would be a travesty to do the latter. Rather than start a fight or develop "bad blood", the wiser choice would be to do the noble thing and accept that they are not open to paranormal discussion and move on.
JMHO....
