Re: The Paradox of Tolerance summarizes my opinion:
"I have, as yet not seen any primates develop an Internet or fly to the Moon. I know, the difference is trivial and the dolphins could probably do the above if they could be bothered, but it still IS a difference at present."
Right. So, you're now telling me that it's OK to kill something for fun, as long as it is seen to be intelligent (however you measure that) than you? They haven't developed an internet or flown to the moon, so break out the machine guns and open fire? If we're really that much more intelligent than them, shouldn't that put a greater onus on us rather than just giving us the right to wipe them out (as mankind has done to quite a few species in one way or another)?
To be fair, I probably didn't put the question quite right. We're talking about murder etc. which is about society and social issues. So, what's the difference between us and animals from a society and social perspective?
