Domesticated camels are nice animals for jobs like this (despite their reputation) but they belong outside.
At the Phoenix show the camels are kept outside until required for the finale of the show. They are then led in, they parade around inside for a bit. They then stand there while a song or two is sung. They then go back outside. Their appearance inside might entail maybe 20-25 minutes total. Each camel was guided by a handler.
Everything else seemed okay to me.
Why not go all out to celebrate the miracle manifestation of the living god into the flesh. The ones upset over the extravagant celebration are those who don’t believe in it. And why do they care anyway?
