By self destruction do you mean- not enough white people?
Well this is the politically correct mindset to try and force the conversation into a protected politically correct category.
Self destruction obviously refers to the cultural identity and being of a people. Race can be part of that.
Because culture is somewhat analogous to race in most of the world then this could be part of that. If you put 10 million Nigerians and 15 million Chinese into the Philippines then yes on the surface the races would change. Of course there would be much more destruction in the areas of culture regarding a set of values and ways of being that has become integral to the Philipino. The Philipino cultural expression instead of being relaxed and comfortable and strong would be under pressure and there would be a breaking point where Philipino culture breaks down and most people turn away from what it has meant to be Philipino.
As an avid traveler who loves the local cultures of many people this is a crime masquerading as a set of ethics. It is thoroughly evil.
