That is what this comes down to. One group in Latvia had the political power to deny another group the benefits of citizenship based on racial and ethnic reasons, nothing more.
Yes. They now had the power to kick out the invaders who had been degrading and destroying their nation and culture. That's what happens when nations enslaved by "multicultural" alien-loving Communism are freed from tyrannical slavery. They take the fate of their nation in their own hands. There are no more Commisars of "political correctness" to tell them what to do.
