This is a good reply and I particularly like the point you make in your fourth paragraph. I note that 40acres made the ideological statement "All politics is identity politics" in their first reply to you. There is a good essay [1] that explicitly rejects this statement and which makes a similar point to yours:
> In practice, contemporary identity politics does little to challenge the roots of oppression. What it does do is empower certain people within those putative identities to police the borders of ‘their’ communities or peoples by establishing themselves as gatekeepers. It has allowed self-nominated authentic voices or community leaders to consolidate and protect their power. As solidarity has become redefined in terms of ethnicity or culture, so those who demand to be the voices of those ethnicities or cultures are afforded new privileges.
