"That again, they respond to stimuli but don't feel pain like an animal."
I don't feel this is a valid argument. We only really know how pain feels to us, but we can guess it also applies to other humans, animals, etc. That we cannot imagine how it feels to respond to negative stimuli as a plant should not invalidate the possibility that it is unpleasant.
