I have bred ('though I wouldn't today), raised, rescued and rehomed snakes from little bitty corn snakes right up to large pythons (part of the reason my family dubbed me "Auntie Crazy"); I would not dance with one, nor would I enjoy watching a show that included one.
Brea, we've talked about our mutual love of animals, so I'm sure you know that reptiles aren't capable of affection. They can become accustomed to certain environments and events, but there's not really any enjoyment factor involved. For me, that nixes performances that use snakes because, in my mind, that's exactly what it would be.... "using" the animal for whatever wow factor was possible.
I dislike other performances that involve exotic animals for the same reason. Zoos, too, for that matter.
In fact, if we got right down to it, I'd ban the sale of reptiles, other exotics, and avians completely, but that's a whole 'nother topic.
