Aggressive and Dangerous is the criteria? I fail to see how that makes much sense. I'm going to be blunt- but if you want to group an entire species/type of snake as "aggressive" or "dangerous" based on reputation you have no business owning animals, let alone reptiles. That's like the idea that pitbulls are dangerous just because of a few bad cases- when in reality you're in more danger from most spaniel breeds.

How are bloods dangerous? Do tell me, how are they "aggressive". I've had several bloods, none of which were dangerous or aggressive. Snappy as babies- but then again a lot of baby snakes are snappy. I've had corns, rats, and balls more aggressive than a lot of bloods I've worked with. Crossing off retics completely? You do know dwarves and super dwarves are out there right? Considering a proper SD retic is far less dangerous than a boa.

You should do some reading and educating. I trust myself and my fiance around my big 16' male retic more than I trust them around most balls/corns out there. It's all up to the individual animal, not an entire species.
