Greek, Norse—It’s All the Same!
We aren’t going to pretend that we care whether Thor is male or female because, to be honest, it doesn’t matter at all. Thor is a fictional character and god that has only become relevant as of late due to the Marvel Cinematic Universe. So, the execs can do what they want with the character they licensed.
But that doesn’t mean other people won’t voice their objections about the sudden gender switch. For instance, this guy was ticked off because he never read about Thor being a woman in Greek mythology. That’s because you wouldn’t find him/her/etc. in Greek mythology, genius.
