From the PETA Site:
So remember, while Zerglings are not real, there are many equally "strange" and exotic animals we share this planet with who deserve our empathy. Just because crocodiles and snakes look alien to us, that doesn't make it OK to skin them alive for a handbag, shoes, or a belt.
And if we had to share our world with the Zerg in reality, I'd like to think that we'd make an effort to understand and respect them rather than sending out the battlecruisers—because the alternative to having empathy for other beings is about as grim as it gets, whether you're a Terran, a Zerg, or a Protoss. OK, whoa, that got kind of serious there. What I am saying is look at the cute Zergling! How could anyone ever want to hurt a Zergling?

I just....

I swear I must be seriously DUMB because I just don't understand PETA and their motives. Part of me hopes this is just for giggles, but I have a sneaking suspicion that PETA is serious about this topic, similar to their serious issue with Mario and his Tanooki suit.
