Also, I don't think the kind of feminism you see online is really liberal feminism even if radical feminists call Tumblrites "libfems". Liberal means human rights, free markets, etc. and the test even describes it as that with Mary Wollstonecraft and the other examples. It tends to be seen as somewhat right-wing in the cases where people aren't just confused by it (although it's really just government based on individualism and not very conservative socially). Tumblr feminism is pretty internally incoherent but mostly based on the
Frankfurt School, if the Frankfurt School's ideologies were the starting phrases in a telephone game played entirely by whiny ascendant bourgeoise (in other words, people the Frankfurt School would hate) adolescents and basement-bound younger adults on the Internet.
