Mass media has hardly every led the culture. Hell, sometimes it barely keeps UP with it. And the reason for that is the simple fact that its primary function is to sell us things. NOT to educate us, or entertain us, much less enlighten us.
Sponsors respond like Pavlov's dogs to the slightest rise in complaints from even the smallest demographic. Why? Because they might not sell as much detergent or shampoo. Even cable stations have to be able to pull in sufficient numbers to justify their costs, and their bottom lines are still at the mercy of their viewer numbers and what amount they can charge for second showings on other channels.
If no one complained about the women on the show being smacked, bit, choked and murdered, then it was reasonablae to assume no one cared, and the sponsors would stay on board. Hint at homoeroticism and heads would have rolled.
And don't kid youselves into thinking that's changed. There's actually more violence done to female characters on TV today than ever before.....but now the women fight back, so that's supposed to make it okay.
