flora - the answer to that is simple.
essential to your argument is that the position of women is deteriorating because porn puts more pressure on women and young woman to perform acts that are sexually degrading. the argument falls apart if only a very small portion of men are actually accessing the material (particularly as I have argued frequently explicit material which we approve of or not has been present for hundreds of years).
search engine stats are provided. a fact. is there anything wrong with the fact? you raise what is left out, critical thinking great love it. but Instead of sneering find search engine stats to support your argument.
I suspect anecdotally from seeing a few porn users histories the porn being accessed is for the most part not as hardcore as woman think.
the person who did access disgusting porn, kept it the most hidden and I did not find the porn until many years after we split. but had so many other red flags I should have left anyway.
but that is the point teach kids the red flags, teach girls the courage of their convictions to walk away. teach kids to report what they are uncomfortable with teach courts to listen better and punish harder.
I suspect the proliferation of hardcore porn is no where near as widespread as mainstream media such as geordie shore which normalises awful relations between men and women. where do you stop? soon censorship becomes the norm and acceptable. I think it's fair to say women suffer the most in societies based around censorship.
but to return to the op. if you are resorting to anti porn literature to remove porn from your relationship you've already lost the argument. porn fan simply trots out the ethical porn argument. objection overcome. and I suspect that this isn't the real problem with the porn else ethical porn would actually solve that.
"No I don't like that" is a complete argument im itself. it recognises the validity of your own choice and opinion - once of the first things that an abusive man removes.
problem is you then give the other person the freedom to say but "I do". at that point either you have to accept a compromise or walk away.
anecdotal evidence suggests a man who uses porn will not stop (it may wax abd wane) but will find better ways of hiding it. if you are strongly anti porn the first time you find it you prob should walk. But that is the same as setting your boundary wherever that may be.
that's to me why educating about consent seems a far more beneficial exercise
