I.....have no idea how to respond to your question.
For starters, your thread title is extremely confrontational and doesn't really relate to what you actually ask of us. Not a good start.
Also, who the hell are the "mainstream gaming press?" What exactly is a "high profile" game? What constitutes a "backlash?" Who gets to decide what a "well-written character" is?
I feel like any response I give that doesn't fit what you want me to say (which seems to be, "Gee whiz, I guess the the media has been making up all this misogyny stuff. Gaming culture is PERFECT!) can be easily shot down since your post is so broad.
So instead, I'll jump to the heart of what I think your post is addressing:
Yes, gaming culture has some hang-ups with women, and it has since its inception. Anyone who denies that is very silly. Things have certainly gotten much better and continue to do so, but it's still a problem worth addressing.
Ethics in the gaming press is also an issue that, like misogyny in gaming culture, has been a problem for awhile, but has gotten much better as both the press and the industry it covers have matured. But I don't think it's near as big of a problem as GamerGaters seem to think it is. I don't think there's a conspiracy within the press to promote certain games, or push a political agenda, or "destroy gamers," or whatever else GamerGaters think is going on (it seems to change depending on who you ask).
The worst ethical breach I've seen is that the press gets too chummy with developers sometimes. I can't get worked up over that. It's like thinking the NFL has an agenda against waitresses because LeSean McCoy didn't tip somebody last week. That's a douche move, but there are more important things for me to get mad at the NFL about right now.
So I look at the two sides of GamerGate: the presumed majority that want better journalistic ethics, and the very loud minority of disgustingly sexist assholes who have upgraded from writing rude things on Twitter to committing felonies. I focus my attention on the latter, because they represent an actual problem in the industry. The former are some well-meaning folks making a mountain out of a molehill.
