feeding in a feeding tub causes organ damage and kills snakes?

[Miranda2]

Now I feed all my snakes in their cages. I do feed hatchlings in small containers as a rule, they always eat better for the first few times.
She was telling another person that feeding in tubs will kill his snakes, causing severe stress, regurges eventual organ damage and death.
I told this person she was overreacting. She got mad and is saying Im an idiot. BTW this was for colubrids if that makes a difference.

So am I an idiot, while its not the recommended practice, Im thinking its not a death sentence for most snakes(at least thats my take).
