Gabbard is problematic as fuck, yes. She is much too far to the right on a whole host of issues…as are most of the other Democrats.
Even on foreign policy, her main schtick is that she actually took the War on Terror propaganda seriously. She wants to turn the Forever War into a serious attempt to exterminate political Islam, rather than just continue to use it as a corrupt and cynical excuse for the usual murderous imperial bullshit.
However, that is not why Gabbard has faced universal hostility from the liberal press. She was attacked because she revealed liberal complicity in the crimes of empire.
