I think one of the problems is that the Women's March (now trade marked in the States) isn't a genuine organisation. By that I mean, a lot of women, not just in the States reacted really negatively to the election of Trump.
Many joined in the Marches on that basis. Not because they thought the organisers were their "leaders" or had a political analysis they subscribed to.
But what it did represent because of the huge media focus on it, rather than say the myriad of genuine grassroots women's groups and individual activists. This made the organisation a target for what I call media feminists, ie women who get their credibility, not from other women, but from the patriarchal media deciding (on a whim) that this is the latest version of feminism that they (the media) want to promote. And of course there are always entryists.
What should have been an amazing opportunity for women to build on contacts that national, or state wide marches gave them access to, somehow became the silenced followers of unelected groups.
It has just turned in to "Event" feminism where you display, usually thought saying all other feminists are wrong, that you are currently the most cutting edge representation of feminism that the media will want to talk to and promote. (Look at the idiocy of them announcing the concept of a women's strike through of all place, the Guardian. Guardian readers can maybe afford to take part in a day of political action and not worry about losing their job or zero hours contract, but most women cant.)
Here is another story about how this is essentially a competive feminism rather than a collaborative one. This is what happens with top down organising. It represent nobody but the egos involved rather than something, probably a bit fuzzy, but is representative of all those taking part.
