I guess it is to be expected that many would say love is stronger than fear.
I too have to agree, and mostly because of the variables involved.
Fear is a very strong emotion. Experience or analysis of a situation (etc.) is pretty much all that is required to induce a fear. There is not much involved, it's simplistic (yet very crippling in some cases).
Love too is a very strong emotion. Unlike fear, there are more factors involved, such as emotions (confidence, trust, passion, affection, etc.). There is a lot that is involved, and a lot to lose should that be the case (contrary to fear, which in most cases is a gain).
It's this complexity, in my opinion, that makes love more resilient with respect to fear. However, the general case is that these types of situations of conflict are never simple.
