I'd agree, which is why the more I think about it, the more the EDL analogy works for me.
And most trans-exclusionary people aren't radfems, which is why I've mostly long since stopped using the acronym. Like the typical edl type, they are people suffering systemic oppression (patriarchal / class-based) who are concerned about the ways in which another oppressed group (trans women / Muslims) might make their oppression worse.
And in organising against this, they end up engaging with some utter cunts (suck my girl dick types / Islamist extremists) and tarring everyone with the same brush, while focusing on a small number of extreme issues (prison populations / hate preachers) which - while they need sorting, don't need some kind of mass movement that tends to demonise the whole group (trans people / Muslims), and at worst, is responsible for its own hate crime and scumbaggery.
