It’s not about the literal meaning of the statement it’s about the meta i.e. how it’s been used in the last decade or so as a way of trying to get away from the uncomfortable challenges that much of the world is essentially forced to react to US beligerence at all levels. So when liberals say Africa is corrupt and that’s why the West has to do what it does and leftists say that the corruption commonly referred to in many African states is actually the result of the the West hand picking the leadership and creating all the incentives for corruption and actively working against any accountability that comes with asserting sovereignty, the liberal will say “two things can be true at the same time” as a way of saying “But I’m not wrong that it’s actually the fault of the corrupt leaders” when in fact the challenge is trying to say that the US is the cause of both the immediate suffering caused by the overt actions of the US and the US is also the cause of the corruption that the liberal is trying to displace blame onto.
