It's human nature to give things that fit your preconceived notions and biases the benefit of the doubt over those that don't, even when you're aware of this effect. The best we can do is try to be cognizant of it and be really self-critical about our knee-jerk reactions.
Assuming it was said by someone fin the USA, there's also utility in this framing. Remaining critical of your own government is pretty healthy for a democracy.
