We will simply live with such accusations leveled upon common Americans with no response (most likely), or we will finally become fed up with such slander and take up arms to put an end to the culture that allows such slander to continue unabated.
Unfortunately, I see the latter as the likely course as those who are being slandered are simply not prepare to stand up to these asshats as a matter of principle, which means matters will only continue to deteriorate and such slander will become “factual” to the majority of Americans.
A national divorce could stop all that, but they won’t allow it.
