As many others, there are points I agree with and disagree with. To me, the glaring disagreement comes from the generalization "west". That goes with "generalizations are always wrong" :-D
Worldwide, there are people that will agree with what you say. And worldwide there are people that will disagree with what you say. I live in "the west" and my personal view is that I abhor the depictions of sex AND violence in the media.
Like it or not, there are plenty of studies that correlate increases in depictions with increases in real-world actions.
What can you do about it? Well, if you are a Bible reader (note: I did not say church-goer) the answer is you can do nothing about it. I am responsible for me. I am also responsible to teach people the Bible's views. If some listen, great! If not, I have done my part.
In short, and in my opinion: Bible prophecies state this world will get worse. Bible instruction says (counterintuitively) we will be happiest if we follow its counsel. Part of that counsel includes non-violence and sex only within the marital arrangement.
