I'm in a weird middle zone here: I almost never pirate anything (I think the last thing I pirated was an episode of a TV show that the local affiliate fucked up on broadcasting so I couldn't see a huge chunk of it on TV), but I also don't think it's wrong to pirate something unless you're causing some tangible harm to someone by doing so. I've already explained my philosophy at length though, and won't do so again here.
What I wanted to say was that any posts I downvoted I did so because of the attitude of the post rather than the viewpoint. Some of the posts in this thread equating one viewpoint to being adult and the other being childish, and similar things, are very condescending. People may disagree on the morals of something, but morality isn't objectively verifiable; neither side is "right" and neither side is "wrong."
You may think it's part of being an adult to recognize you can't have everything you want, but others would argue that that is a concept that is outdated when applied to infinitely reproducible digital goods. Neither viewpoint is wrong, they're just different. Calling someone childish because they don't hold exactly the same moral beliefs as you is not doing anything to advance the conversation.
