I'm not convinced. The coalition of leftist politics, interest groups, government, main-stream media and some crony capitalists have convinced a good part of the USA population that the multi-culti, PC nonsense is a new, sacred religion.
Right now, multi-cultural touchstones have been burnished with the mantle of virtue. But that's only because the controlled media never explained the cost to liberty & freedom when the state is used as a tool for personal design.
Just wait until the counter-attack begins; the narrative is easy. Open borders is merely the device used to exploit wages & labor ie the working class. It also enables its proponents to engage in human trafficking for personal gain.
In other words, the left represents tyranny, while the right offers liberty: of association, of belief, of freedom from force & fraud.
Once PC anti-free speech & safe spaces are cleared out of the universities, the slow process of changing the debate back to the principles espoused in the founding documents can begin.
The process will be complete when the individual is once again elevated & virtuous, while the state - and all who would use political leverage to gain personal control - represents oppression.
