The plan to reduce the white majority to a minority is right on track. Liberals do not think that it is fair that there is a white majority in this country just like they don't think that it is fair that the US is the only superpower. White liberals suffer from a profound sense of guilt. They will not be happy until they themselves have handed over their own political power and influence and they themselves have been reduced to a white minority. Then and only then will they be happy when they are riding at the back of the bus.
I think your analysis of white guilt is largely correct, with one large exception.
White liberals, or elite white liberals I should say, have no intention of giving up their power or going to the back of the bus. This is the fate they want for fellow whites who dare to hold more traditional values, and who don't share that paralyzing sense of white guilt. It is these fellow whites above all else that elite white liberals hate and must be superior to.
So I would agree that they suffer from extreme White Guilt, and that they hate their own culture and traditions and legacy and heritage, but I think they see the Democrat-friendly demographic shifts as a way to finally gain permanent dominance over those other whites who don't share their shame.
I don't grasp the insecurity. Why is it important for white people to outnumber all the other races combined? Explain this one.
