I adore my snakes, and they are more relaxed around me than someone that they don't know - however, I don't delude myself into believing that they "love" me. I know that if they were allowed to free roam and were put down outside (or in), that they aren't going to seek out my company. They'll just go on their merry way.
If it makes people feel better to believe their snakes love them, and it enhances how they feel about their snakes, I have no problem with that.
I simply don't require reciprocal love from my snakes to adore them myself.
