> Multiple humanitarian organizations define mass displacement as genocide and/or ethnic cleansing.

You're mixing two things here to your advantage. Genocide is (or can be) ethnic cleansing but ethnic cleansing is not genocide. So your "and/or" does some work for you there and makes you correct. However, you said genocide not "genocide and/or ethnic cleansing". You've moved the goalposts.

It'd be odd to redefine any word that ends in '-cide' from actual killing.

> The holocaust literally started with mass deportations/detentions.

Which was ethnic cleansing.

> Then the nazis figured out that it was easier to kill detainees.

Which was the point which it became a genocide.
