This is so much longer than I expected it to be, but I did think long and hard about it. Let me preface this by saying that although I express my opinions in pretty definite and assertive terms, they're still just opinions. You're free to agree or disagree, and I'm not trying to invalidate your concerns. I'm hoping to provide the perspective of a relatively neutral third party: a gay man who tends to relate more to women in these types of situations.
I have trouble understanding why the lack of strong female characters is an excuse to condemn anything with strong male characters. I go out of my way to watch movies with empowered female characters, and there are plenty of great action movies out there with a strong female protagonist. So I think it's perfectly acceptable for there to be movies that indulge the hetero male fantasy. Personally, I don't think that Kingsmen does this at all. I think it pushes boundaries and bypasses convention. But clearly, you either believe that it doesn't break stereotypes or that it doesn't to it well enough, so in the interest of argument, I'll accept that opinion as the basis for what I'm about to say.
This is one movie that favors men because it was designed to favor men. The title is Kingsmen. The target audience is men. Men love action. We love spy movies. We're the ones paying for the tickets to see this kind of thing. If women were breaking down the doors to see these types of movies, maybe things would be different. (Though I am totally willing to accept that we'll never know whether the audience shaped the art or vice versa, I still can't help but notice that many box office action hits with female leads have a primarily male audience. See: Charlie's Angels, Kill Bill, Alien, Terminator.) I'm not saying I'm an expert on the topic, but I find that heterosexual men tend to like action-driven plot while heterosexual women tend to prefer drama-driven plot. There might be some science behind this, but I don't know enough about it to say for sure.
Now, maybe this is a controversial opinion, but I don't think that every female character in every movie needs to be Katniss, "The Bride", Ripley, or Sarah Connor. The strong man/weak woman stereotype can be just as fun as the strong woman/weak man theme. To say that we need to weed out the former because there's not enough of the later won't fix the problem. We'll just end up with less of everything overall. It's like looking at a birthday party and saying, "Hey, there's too much cake and not enough ice cream. Let's throw away some of the cake." Screw that. Let's just get some more ice cream and have a real party!
On one hand, I can see where you're coming from. A movie that is supposed to be aimed at men is telling men that men are the stronger, better sex. I get that. It's self-indulgent. It's a circle jerk. As a gay man, I feel both empowered (to see a man doing great things) and dismayed (to see that he's always heterosexual). But I'm also not the target audience. When I want to find strong gay male characters, I look for shows and movies that are targeted to me.
In my opinion, we should let straight guys have their testosterone-fueled action flicks. It's their guilty pleasure, and I think they're entitled to it. For every one of those, there's a sappy chick flick that inaccurately portrays men as being head-over-heels in love at the drop of a hat, licking a woman's boots to be with her while wearing far fewer shirts than any man has any business wearing. Objectification of the opposite sex is fun and indulgent, and Hollywood will never stop doing it. The recent uprise in the media objectification of men is an excellent counterbalance, and I hope the trend continues.
If you want to find the real problem, look for all of these movies that are aimed at women (or worse: young girls) and simultaneously make women look like worthless pieces of crap who need to be rescued by abusive men. (I'm looking at you, Twilight and 50 Shades of Grey, you woman-hating monsters.) Empowerment comes from within, and these movies are designed to prey on female insecurities. If I can make an attempt to relate: I'm rarely affected if some idiot straight guy calls me a faggot. I assume that he's insecure, and I dismiss him as a bigot. But when someone from within the community attacks me and insults me because I don't fit their definition of what gay should be, that hurts a lot more. I'm supposed to be able to trust my community, and instead I feel betrayed. More similarly, I hate when I find a movie in the "Gay and Lesbian" category on Netflix that seemingly has nothing to do with sex, start it up, and find myself bombarded with a sex scene between two men every ten minutes. I hate the hypersexualization stereotype of homosexuality! But these movies aren't being made by heterosexual directors. They're made by people who I'm supposed to consider "one of us."
Are straight men responsible for much of the inequality in the media? Sure. But I don't think that's nearly as damaging as something being written by women, targeting women, and simultaneously demeaning and degrading women. I hate seeing women do that to themselves, and I think the focus should be on people who propagate this kind of thing.
I'm sorry for the long post, but thank you sincerely for reading all the way to this point.
