Oh, so the exhibit is done with live animals.
Well, now I understand some of the objection.
It’s not a knee-jerk snowflake response at all.
No, sentient, domesticated animals should not be used in such a manner. If we were talking about Japanese Fighting Fish facing off, with one fish per it’s own glass bowl, that would be somewhat different, so long as they could move around a bit for tension relief.
I read elsewhere that the exhibit is a video recording of an event in China in which the animals never touched each other.
Then they ate them. Just kidding.
