Eh, I'm not so sure, seems to me like it's too convenient to just blame "media" for a subset of people who are deeply flawed to begin with.
I think the dysfunction happens first, with the person in question picking and choosing media that reinforces/comforts that broken worldview second. I don't believe that exposing a person to highly idealized media images can make them unquestioningly believe that image over reality if they didn't already have a tenuous grip on it to start with.
I mean, I feel very confident that most of us here can realize the plots of romantic comedies and harem animes for the fun little fantasies they are, completely unworkable in real life. But where you or I, after the credits roll, can say "well, that was fun, too bad (or fortunately?) life isn't like that" the Nice Guys instead think "Women should watch this stuff so they can LEARN how to act! I'm doing MY part! I'm the hapless guy fawning over her from the shadows, just like you're supposed to, and she STILL doesn't come to me!"
Media doesn't create these people, it just lets them indulge in their bitterness.
To me, that's like blaming "violent" video games for creating mall/movie theatre/school shooters by teaching them it's okay to blow away people for fun, when I think at this point it's pretty obvious to everyone except moralists and maybe Jack Thompson that no such link exists. They REALLY tried to find one in the 90's, believe me, and not just the parents either, there was an honest belief in academia at the time that generation X was, if not one itself, going to certainly give birth to a new class of "superpredatory" criminal..
Why?
Because, well, media was so darn violent! Just look at these TV shows! And video games!! And comics!! It was only natural the generation raised on it would turn every main street in the country into Mad Max once the current generation got too old and feeble to reign them in!
The unsaid assumption, of course, is that everyone, save a select few, are dumb sheep who'll do whatever the cool guy on TV does without thinking about it.... if he buys a Pepsi, so will you, he drives a Toyota, so will you! And if he shoots that woman who reject him, so will you!
Yeah...
It doesn't matter what you wave in front of me, be it boobs or something else, I don't drink Pepsi because I don't like the taste, I don't drive a Corolla because I think they look like ass and I'm not going to shoot a woman who won't fuck me because I'm not a psychopath.
Media is a powerful force, but, it can't turn people into something they didn't want to be in the first place.
There are a few clueless types who have genuine social awkwardness and DO look to cartoons and movies for dating advice, but they eventually come to realize that stalking a woman to show their affection is, well, creepy. And they usually realize at some point that they were foolish for giving that much credulity to media-depicted romance, whereas the Nice Guy continues to sulk and wonder why women are too stupid to follow the script.
