I really don't believe there's a thing as too far. I don't agree with every message in every song, but I also believe in freedom of speech and expression. I don't have to like it or support their message in any way...but I also don't have to listen to or watch something either, do I?

If you're really concerned about whether or not something is appropriate for you or your family, do the research. It's possible to even find out something you formerly supported (like Hannah Montana) is something you no longer want to support (backed by your hate for Miley Cyrus' supposed "raunchiness"). It's okay to no longer support something and speak out against it, really. What's not okay is imposing bans on what other people can and should be listening to.

I understand the whole "BUT I STILL MIGHT HEAR IT OUT IN PUBLIC!!!!" So don't frequent those places. It's pretty simple. And if you're just hearing someone swearing or talking about things you don't agree with in public...I mean, again. This is a free country and people can talk about whatever and however they damn well please, even in public. You don't have to actively listen to their conversation. You don't have to agree or like what they're saying. But it's really stupid to get offended when no one has done or said anything offensive to you. And if there are children around, explain to them that those aren't your values, or values you want them to have. The onus falls on you as a parent/mentor to teach children (what you consider to be) right from wrong; the onus does not fall on society to pad and shelter people who can't deal with things they don't like.
