You don't like looking at it? Don't watch, simple as that. So long as equable standards of decency aren't being breached, I don't see why you simply can't look the other way.
Keep in mind that words like norma/abnormal are relative terms. What you find normal may be abnormal to someone else. What you find abnormal may be normal to someone else. You're entitled to your view but you must realize that it is an opinion based on an opinion, and not necessarily an opinion based on fact.
The real issue here may be your own personal frame of mind. You may have had experiences of some sort - I'm interested to know if that's the case. A bad experience can traumatize some people.
