Okay, I'm not a vegetarian. But I still see this as cruel. Plus why would they want to waste time doing that anyway? What kind of sick person thinks of beating a bat as something fun to put up on the internet? That's below Jackass level!
And I know how you feel. My mom's reaction to finding a snake in the yard is to call one of my male relatives to shoot it, even if it might be harmless (I don't think we've ever had a venomous snake in our yard). Got so tired of it that one time a snake slithered right in front of me while Mom was within shouting distance and I didn't say a thing. I let it go, and no one saw it again.
