If everyone did it, yes. But if some people refuse to care about gender while others are making attacks over it, no, they’re just denying the problem. As it was said: things like misogyny and racism do not go away because people stop talking about them; they are only reduced when people confront them.
Healthy people won’t have any bandages, but that doesn’t mean leaving them off is a sensible response to an injury. So it is with paying attention to identities in society.
No doubt, but that doesn’t change that gamergate right now is a prominent manifestation of that misogyny. People should be concerned about the attacks being made on women like Sarkeesian and Wu, and this happens to be the banner those are currently under.
Edit: also, I don’t want to go against you for ideological purity here, but I couldn’t help but recall your last position was that these threats weren’t reflective of any real misogyny problem. That makes it very hard to know what I’m arguing against when you advocate ignoring the movement connected with them.
