Sorry, but both the points you attempt to make here are really weak, to the point of being transparently silly.
I'm glad to hear at least that you have reservations about the concept of animal ownership. The fact that someone's "ownership" of an animal entitles them to do to it whatever they like just has to be morally repugnant to anyone. Do I own my two cats? And if I do, should I be legally and morally entitled to torture them? If you really think that's okay, then I don't think you'll find too many people to agree with you - for which fact we should be grateful. I do hope that's not what you really meant.
As far as the analogy with plants goes, that's just totally lame, imo. There's no scientific basis for assuming that any organism without a complex nervous system can suffer in the way that, for example, any mammal can. If you genuinely believe that digging up potatoes is in the same moral category as slaughtering a cow, then we're just going to have to differ,
I never said I condone torture or I thought it was OK to torture. Anyone sick enough to torture is not going to worry about laws or morals.
I'm talking about people who tell me I'm being cruel to my dogs because they live outside. I'm talking about people who take a very good and just cause and turn it into a joke by taking it to silly extremes.
As silly as the idea that a plant has the same standing as a cow, which according to some, has the same standing as a child.
