>Our brains are not that different than other primates' brains. We do abhorrent things to other primates that __demonstrably__ have similar experiential qualia as humans, mostly for the benefit of our species. But somehow objectioners are losing their marbles over a human cell cluster that has no more than a few thousand constituent cells.

This is some kind of strawman. I'm confident that people who are against human cell cluster torture are also against primate torture. Or at least make the mental calculus required to justify it.
