[Socialist Worker Online]
A DIFFICULT test of one's moral character is to always look beyond difference and prejudice, and recognize the value of another. It is always easier to show kindness to one is who similar and to one who is like you, but the real test is to stand up to the rest of society and stick up for those who relate to you the least--those who you understand minimally.
This is true not with just humans, but with all. No matter how challenging it may be or how ridiculous others may like to make it appear, we must bring ourselves to a point where we can widen our circle of compassion to encompass all who are deserving of it, regardless of their biological species.
Paul D'Amato (whose work I have tremendous respect for) makes the
argument in his article "Socialism and 'animal rights'" that no nonhuman
animal is worthy of rights on the sole basis that they don't have the
capacity to comprehend the meaning of rights, or solely because they are
unable to fight for their own rights themselves.
