Butt stain thinks he's an expert on everything, and like the deranged loon he is, a silly meme triggers his stupid.
If the meme was silly, why did you post it?
What makes the meme silly is that it wasn't accurate. We have no idea what Cain killed Abel with, and Goliath doesn't sound like that bad of a guy. (I also don't think he was a giant, because Giants aren't real.)
