“What would be considered”. Sorry
I help out with the youth group at church and one of the students is in the 10th grade and he is pretty retro (loves movies and tv shows from the 80s and 90s). He used to be a big Star Wars fan and lost interest due to "disney making it a princess product" as he puts it. He was asking me the other day how did all this happen or when did it start, and I couldn't pinpoint an exact person who started this but had some ideas.
What did start it all? I know Ghostbusters 2016 seems to be the first movie to actively be made to piss off fans (when the original director was trying to do Ghostbusters 3 and they screwed him over). With Star Wars, if they wanted to appeal to actual women who were fans they could've used Jaina Solo or Mara Jade.
Was it in gaming? I remember when gaming magazines seemed to have constant articles about women in gaming or about the "abuse" they received online as if they have never heard the language you hear where guys get together and hang out.
Comic books? I mean they literally made comics of women sitting around the table discussing feelings and as Eric July said "modern comics are made for 14 year old girls on tumblr who don't read comics"
So honestly who is patient zero or who is to blame?
the existence of liberalism
These people aren't liberals. Liberals believe in total freedom of expression and that people should be allowed to make whatever media that they want, no matter how offensive and sexual it may be. These people are radical sex negative feminists, like Andrea Dworkin for example. They really hate male sexuality and would probably remove men's libido from humanity if they could. They will forever seethe over the fact that men like women's asses and titties. I wish people would call these people out for what they are, man hating feminists, rather than liberals or whatever term boomers use.
Feminism birthed from liberalism though.
It's a far left ideology. Feminism is literally incompatible with libertarianism since feminism advocates for state measures and authoritarian rules to be pushed by the government in their favour. Their whole ideology is crying to daddy government to get what they want, which is what liberals are against. Hell, regarding the topic in this thread, feminists would absolutely love to ban any media they deem "sexist", which liberals are very against. Overall, feminism is an ideology that believes in equality of outcome, which liberals literally oppose greatly.
The idea of opening up men's domains to women is inherent in liberalism though. Marxist types just came along and added more force to the notion, not that liberalism doesn't become forceful in its own right anyway.
