I consider myself more conservative than not. I have no issue with female characters.The reason why conservatives like some female characters and not others is often based on the ideology and politics in a movie and show and also whether or not the movie or shows they are in also have a well rounded and strong male character as well. Ripley had Bishop and Hicks. Sarah Conner had Kyle Reese and Arnold. Wonder Woman had Steve Trevor and the list goes on.
People keep thinking it's about the women just being in the movies/shows that is upsetting them but it's actually about the male characters being or not being in the movie or show and their actual role in the story and also the political themes of a movie and show and how Overt they might be. Not to mention they have a harder time complaining about movies and shows that are truly good so they really go after low hanging fruit such as Ghostbusters 2016, the new Disney SW movies etc.
Could be an entire female cast and wouldn't bother me.
