Earlier quoted context omitted.
I'm just showing that the argument can easily be used to draw the opposite and "wrong" conclusion from the one that was intended to be reached.
You should reach a conclusion based on your beliefs. I don't see what point you prove by starting from beliefs you don't hold if that's what you mean. Do you genuinely not care if people are killing dolphins and whales and eating dogs though? I've no doubt some people exist that don't but I'm sure they're in the vast minority.
No, but I do genuinely not care that people are killing and eating cows and cow products though. I don't really think anything could make me care about that at this point, certainly not enough to give up meat and cheese.
So if we are making these things equivalent (which I don't believe they are), then I suppose I shouldn't care about the dolphins, whales and dogs. In order to be consistent.
