> I do think that plants have capacity for suffering but it is incomparable to the suffering of a cow, for example.
why? why is it incomparable.
the fact that you even consider "genetic relatedness" or "that plants have capacity for suffering" is an expansion that requires admitting a simpler view that many vegans have was simply wrong! there are plenty that are like "anything without a central nervous system can't suffer!" and the goal posts keep moving as they have to accept that more and more organisms avoid negative stimuli because they can predict it or don't want it.
if plants could yell and howl in pain they would. which way would be incomparable?
if plants could uproot and move out the way, they would. which way would be incomparable?
and that entire view is based on the vegan feeling so uniquely enlightened, as if the rest of us could not perceive suffering of mammals or suffering of other species. but it was only you, the anti-suffering vegans, that ever needed the validation of additional institutions to accept this already widely held perception that killing organisms for consumption is something those organisms actively react to and avoid because of sensory inputs.
and for solutions, it is arbitrary to manifest that as a dietary preference.
