This caravan is probably 80% women. And the grassroots movements in the US, with the Women's March, and in all of Latin America, are being led by women on the ground. This is not a coincidence. It's not exclusive to women, but because the kinds of jobs we do in society, and because of the human history of patriarchy - women have a hugely important contribution to make. Not just in the rank and file, but in leadership positions as well.
