So who would be the anti-DC crowd who also happens to have a feminist bias, slant, or focus?
I have no doubt that there is a set of vocal anti-DC people. Likewise I have no trouble finding people calling for more female representation in superhero movies. But I think any actual overlap between those two groups is near zero. On the contrary, I have found that the anti-fans I've encountered predominantly are steeped in male or white privilege.
