My point is, violence is OK on TV, but even just showing a naked person, is wrong.

The discussion is not about what's on tv, it is about what sexually arouses the OP significant other.

In Germany there are boobies on tv, during the day, maybe in a showergel-ad or something, and nobody complains about it. But some of the most strange porn is produced somewhere in the US

Are you serious? The main two countries known for the strangest porn in the world is Germany and Japan (which show titties on tv)

most porn found on a guys harddrive is the standard stuff

We aren't talking about most guy's, we are talking about a particular guy.

, and other people there are pretending sex doesn't exist... Or if, it exists only for reproduction.

Let me educate you a bit because you have a major misconception about the united states.

As a country we love sex and violence. There are very vocal minorities in the united states that are against sex and/or violence. They do not want to be exposed to one or the other in their everyday lives. The rest of us don't give a fuck, we just want to be entertained.

So how do content producers deal with the vocal minorities? They came up with a rating system. The more sexual or violent superstitions you have in your content, the higher the rating. Higher rated content is shown at times and from sources that will be likely exposed to the vocal minority.

Content producers want their product exposed to a many people as possible, so they curb their ratings lower. They cut the unnecessary violence and sexuality from their content. Guess what? Most sexuality isn't critical to a story. So that is what gets cut or toned down the most (most of the time).

Now I'll admit we do sexualize the breast, although this is changing. But by an large most americans don't mind seeing a pair of titties and think of those that do as prudes
