You pretty much nailed it. In the case of Anita Sarkeesian she needs to apply a process I learned way back in my my higschool art class. It called contructive critcism. You don't merely point out what you don't like. You explain why you don't like it and how you would fix it. And its a take it or leave it approach. But like you said, I don't think she is bringing this issue up for the right reasons or using the right approach.
