At what point did you stop being the invader and become the invaded? Conceivably, someone could have held the same sentiment about someone more vunerable in your lineage whose efforts leave you where you sit today. I favor giving that person a chance and not labeling them an invader. I believe that's what's outlined in the rulebook here (the United States for me).
> At some point you go from becoming diverse to being supplanted. Immigration rates high enough to drastically change the culture of a society within the lifespan of one human being can be catastrophic. It naturally creates division and strife.
This line of thinking, positioning and labeling I consistently find troubling as it leads to violence against minorities justified by often false, purposeful anecdotes without consideration of the policies and practices that cause inequality. That's catastrophic.
