Are you saying that lgbtq (and whomever else may feel "marginalized") would all be considered Dalit? I don't know enough about the caste system and distinctions that go into it.

And how does India teach Dalit history? is it separated somehow from history taught to other castes? Just curious - trying to figure out how different the ideologies actually are on this point.

The original article was written in the US, discussing US/western practices, however I don't know that anything I stated, while definitely intended for a western audience, is any less true within other ideologies. That said, a more collectivist ideology might prefer to be indoctrinated through state/statist education centers, and may thrive on this path as dutiful members of the collective.
