But the question was if “more intelligent” gives us the authority to eat them, or make them go extinct by destroying their habitat, or abuse them for medicine trials.

And if “more intelligent” is a valid reason you are immediately entering a weird area where it is okay to eat a baby because hey, it’s less intelligent! But I doubt many people would think that’s a valid reason, so we’re back to speciesism. which is also problematic because then we appoint the human as sole judge and juror of all living things.

That's a separate question but not the one any of the posts I replied to were addressing. I don't think it's honest to attribute to shield properties they don't have simply because you don't like the implications of the reality.
