I feel that way too. I’m worried about how far they’ll take Demon!Dean in season 10 with being a womanizer. The thought makes me cringe.
But, it’s still my favorite show.
Everyone has a line, and if a show crosses it, they have every right to step away. For several people, the misogyny and queerbaiting in SPN have already gone too far. And it definitely has, but I don’t think the people who are still watching should be criticized for it.
A lot of media is problematic, and as long as you can acknowledge that and are critical of it, there’s no reason you can’t also still enjoy other aspects of the show.
