Not at all, how does that even relate to less worthy in your mind. Being non religious could mean they sin more and as such strum ga non beloved might cause more temptation to sin. That is all nothing more and certainly not what you are suggesting.
What a silly comment you would turn down the love of your life because they are religious. My dads agnostic at best, not sure exactly his views as he doesn't seem to have any, mums religious they get on great and is treated like any other hobby that you may not enjoy. You compromise and support your loved one in any aspect.
As to your second comment, I think there has been miscommunication.. I didn't say I'd advise not to be involved with someone because of their religion.
I dispute the notion that just because someone belongs to a religion, that somehow prevents or precludes them from commiting what is theologically termed -- a sin!
