The way you phrased your sentence about piracy was biased against pirates. You were saying these moral choices aren't similar, I'm trying to refute that, and I'm saying they are similar.
It's not even current memes. If all my co-workers watched some obscure regional television decades ago, how am I supposed to understand the references they make without pirating the media? At what point do these creative products belong to society instead of a specific individual?
OP is talking about how there's a different perception of the morality of these things, and the lesser harm(pirating) is being viewed on more harshly than (not being a vegetarian). This is the core of that discussion.
