South park and buffy is more sexist. Even Dr. Who is more sexist. There are disproportionate number of women only concerned with the dr. in that show. TV in general is very sexist.
Though it's easy to see how some guys who don't want to see women as full characters would grasp at straws to claim that a show that many women like is sexist. However, they are wrong. They must think that showing strong capable women struggle the way men struggle is wrong. Perhaps they think it is sexist because
Supernatural had a vital seer, who was nothing like the traditional version of beauty. Perhaps they are threaten by less attractive actually making their way on to a highly successful tv show.
This blog (spoiler alert) http://www.kissmywonderwoman.com/2013/10/supernatural-is-sexist-and-misogynistic.html article rails against a perceived tendency of the women in supernatural to die, completely ignoring that EVERYONE IN THE SHOW DIES. Also if people want to attack shows for being sexist they should probably start with the others this person listed as being great. Game of thrones is horribly sexist almost everyone women in the show is obsessed with a man. There is only on really strong women in the books all of them are terribly unrealistic. Most are just used as pawns for their literal vagina. How is that less sexist than killing all the women in the same way all the men are killed. Elementary and next top model are even worse.
This blog is not the only one of it's kind there have been a terribly large number of them. Must be a misogynistic demon.
