So, did Marvel Comics take a cheap shot at #Gamergate?
This appears in the most recent issue of Loki: Agent of Asgard.
Speaking for myself, I don't buy it.
Perhaps if this quip had come from a character such as Tony Stark that would be one thing. But the quip comes from Loki. Not only a villain, but the single most treacherous and deceitful villain in all of Marvel Comics. A character who, as he is literally the God of Mischief, would likely look at all the chaos and discord social justice warriors have sewn in the world and approve of it.
Taking character motivations into account, even if writer Al Ewing intended to take a shot at #Gamergate, that's not the message that realistically comes through.
As for female Thor: as I understand it, the objection many comic books fans have raised have less to do with the actual change, and more to do with the contrived way in which it was done.
Even then, everyone needs to relax. The idea of Thor as a woman has an interesting novelty. For a time that will drive sales, then when the novelty is gone Marvel will change things back.
Remember, this is the company that couldn't keep 90-year-old May Parker dead (bless her fictional soul).
