Well, yeah it is?

If you're demanding for dominion over land based on ethnicity only, you're asking for racial supremacy.

If you're arguing for a leadership/institutional change but not demanding one race hold dominion over land, you're asking more for an imperial regime.

There's nothing wrong with either as it's the recognition that some cultures and ethnicities can't live with each other while the latter is recognition that some cultures work better in leadership positions than others.
