This Extension will reverse the genders of any website you read. He becomes she, Feminism becomes men’s right activism et cetera. On top of that there are alternative settings and wordlists you can choose from like MenKampf and GamerGate.
It works great with most slang and typical feminist or pick-up-artist lingo. As opposed to similar browser extensions GenderSwapper will attempt to preserve the original text and grammar as well as possible and is frequently updated. While it’s not perfect (for example it can be hard to figure out for an algorithm if “cock” refers to an animal or human anatomy in a vulgar manner) you’ll be surprised how well it works!
You might love it because it’s absolutely fantastic to highlight double standards and the hypocrisy of tabloids and social media.
