Fair enough. But this happens in every biologically relevant discussion.. Every time results are reported on mice, someone will criticize that it wasn't done on humans, as if biologists are complete ignoramuses and not intimately familiar with the strengths and limitations of their own science.
If an engineer presented a model of a bridge and someone jumped in to say "buh, but you didn't ACTUALLY BUILD the bridge so this is worthless", people would rightly tell him off, wouldn't they? Why is this low-effort criticism of biology allowed ?
