Also, just as important to see what people say, is to see what they don't say.
They're complaining about a female leader, while citing other female leaders as 'bad examples'. Male choices that are on the same level as Tubman (Mach, Battuta, Rizal, Confucius) aren't mentioned at all.
Those that do this don't communicate that they have a problem with outlandish leader picks, only with the female ones. This is sexism, and that is not FXS's problem.
Not every screenshot posted contains such nonsense, and those absolutely can be seen as genuine criticism.
