If you can't acknowledge that the complete eradication and deliberate destruction of an entire race counts as an act of genocide then there's not really much room to see eye to eye, is there?

The Sundering was very much an act of deliberate genocide and no amount of screeching or preaching from the protagonists or those that imprinted upon the pretty mother goddess figure is going to change that.

It's a statement of fact, not opinion. If you completely wipe out an entire group of people and then work to obscure any knowledge of their existence and replace them with completely different beings altogether...then that is very much genocide at play.

Much in the same way as how the Rejoinings would inevitably involve genocide as well.
