Speaking as someone who doesn't watch Supernatural at all, but has been glancing at the debates...

...you seem to have missed the point.

It's not, "The mean feminists are making little old me feel bad!" but, "It bothers me when people make arguments that impose a value judgment, particularly a contemptuous one, on those that disagree with them."

Which is exactly what you are doing by characterizing people who are unhappy with Supernatural for feminist reasons as "flipping out over a few words in a character's mouth."
