I believe the correct term is humanist. A humanist wants equal rights for all human beings and not just certain groups based on certain characteristics. Does not claim one group is superior to another.
Feminism used to be different, it used to be like humanism, now I see it as a tool to tear down white straight men and claim women are superior and deserve special treatment. I didn't always have that view, but after seeing a lot of Feminist groups attacking Hacker News using hoaxes and untrue statements I eventually came to that conclusion. I have never seen Hacker News or YC discriminate against women, and anyone who posts a sexist statement gets downvoted.
I think on 4Chan and Reddit a lot of these sexist men are really boys under 18 who are not mature yet and hide behind an anonymous name to lobby death and rape threats at women. I just don't see that in Hacker News or YC, when men are mature they don't do those sorts of things.
So yes sexism does exist and there are issues, but not everywhere. The word Feminism in itself is sexist because it only mentions the female gender and there are more than male and female genders out there. Hence Humanism would be a better name or Equalism because it does not mention gender.
I want to state that equal rights is different from special rights and entitlements. If anyone wants a career in IT, they have to study hard at math and science, they have to work for years to become an expert sometimes as many as 15 years. You can't just avoid studying hard, blow off math and science, and then study arts instead and then claim you are owned a job in IT because of your gender. If you want a job in IT, study math and science instead of art, keep learning and gaining experience over the years to become better so you can get a job. Communication is a key, and about 80% of the job. If you cannot communicate with others effectively and keep using the terms mansplaining when something is over your head and you need help with, it isn't going to help the team and make you look bad.
Admiral Grace Hopper, Ada Augusta Lovelace, Sister Mary Kenneth Keller, and many others studied hard, worked hard, developed the experience and skills they needed and didn't have anything handed to them, or were entitled to anything, or required special treatment. They just studied math and science, studied hard, worked hard, and reached their potential to develop the experience and skills they needed to do what they did.
