I've been to LWS events - which are brilliant and proper grassroots activism, though obviously the mainstream media won't admit that or report much on it. Just because we don't hear about this doesn't mean it's not happening. It's part of the misogyny of the media.
But, like many women who know what a man is, i am middle aged with children and caring responsibilities. Some days I barely make it through the long list of things I absolutely need to get done or something dreadful will happen.
I need to arrange childcare / child transport somehow if it's a weekend because DH can't do all the clubs on his own as each child is in different places at the same time. OK, they can miss the odd club, but it's not realistic for me to be doing it regularly. It costs money. I don't have pots of money (sadly) - I have to decide whether to pay into a crowdfunder or for a ticket to London (or wherever) to protest.
For women with small children, who are breastfeeding, it's even harder. Women who are caring for elderly relatives without sufficient support - there are lots of women in this position - ditto.
Older women with infirmities or disabilities or modest incomes can find it difficult to travel too.
The young transactivists have none of these issues because they're not the ones propping up the economy with unpaid caring work. A feature of the transwidows threads is how little the men wanting to be 'women' do of all the unpaid caring work that falls overwhelmingly to XX women.
Also, having been to LWS events there is no fucking way in hell I'd bring a child there. Some of the masked men trying to shut women up look as if they'd like nothing more than beating up a woman. It can be scary, and the policing of these events has been variable - sometimes good, but sometimes they've let women be attacked. We all saw what happened to Kellie Jay in New Zealand, and the elderly woman punched in the head by a young misogynist man. I think some women put their physical health first.
So I think the reasons why more women aren't on the streets are varied and complex.
Part of it is undoubtedly that women don't feel supported by the police to do so safely though.
