I have run into this negativity. We all have. Truthfully I would prefer a snake (and I do) over a dog or a cat. So what if they dont show us affection or play fetch. The biggest reason why there is so much negativity towards snakes, even reptiles and arachnids is the media. tv shows, movies, news, all of that never shows the real side of the reptile hobby.
I for one love all animals to matter what. I will not hate an animal for its actions or what it can do.
