I find The history of the different feminist factions to be very interesting and in particular I find the split between equality feminism and difference feminism to be one of the more significant event that illuminate much of the inconsistency of the movement that we see today. The older equality feminism view was that men and women are significant more alike than different and should thus be treated as identical androgynous humans, while difference feminism view men and women as different but deserving of equal power. The modern feminist factions are largely descendants of the difference feminism view so we get occasionally modern feminist that claim that women can not be sexist since men has more systemic power than women. It follows a kind of logic if one look at gender as uniform groups that wield power.

Still all those factions exist and so do the older equality feminism even if its just a minority today. The sad thing is when infighting occur, the common suggestion is that the other side is automatically far-right for not agreeing. I would suggest that this is why "the modern feminist movement" is starting to see more like a uniform set than different factions.
