Some of them. Most of the community is mestizo. And their ethnicity has literally nothing to do with it at all. It isn't an indigenous movement, it is a community protecting itself. Do you think the non-Purepecha residents don't count? That they were not part of this action?
>all the news coverage points out that the initial uprising was initiated by women.
No, plenty of news coverage is factual. You're just looking at the "news" that is trying to use it as a feminism story.
>anti-colonial: outsiders of a different ethnic background
The outsiders have the same mix of ethnic backgrounds the community does.
>Before the government didn't take us [women] into account
Notice how the word that is necessary to make that sentence mean what you want was inserted by the "journalist", not said by the person being quoted? "Before the government didn't take us [the people] into account..."
>It doesn't "suddenly occur", it was always there
It has never been there. There are actually several anthropology texts on the Purepecha, they were never matriarchal or anything remotely resembling it. Nor were the Spanish, although there's not much in anthropological studies on them.
