Actually, Tapper is on to something here, but doesn't know how to discuss it without doing exactly what he did (step into a minefield).
Liberals do have a disconnect with the military because they look down on that "warrior" mindset instead of marveling at and regarding the patriotism that motivates it as a precious human attribute.
They will utterly wreck the military with their PC swill and then wail when there is no one to defend the walls when the city gets sacked by the barbarians.
That day is coming.
They won't wail - they're the fifth column.
