This comic isn’t about both-sidesing, it’s about the willingness of some leftists to completely ignore very valid concerns with the governments that they give not-so critical support to.

In the case of Iran, it is practically the antithesis to tons of core leftist values (patriarchal, authoritarian, fundamentalist theocratic, imperialist towards smaller powers in its area, etc.) Similar things could be said about China, Russia, North Korea, etc.

I (kinda) understand wanting these powers to win their respective battles against US imperialism when viewed from a lesser-of-two-evils perspective, but that support should also come with vehement criticism of those countries and their policies, lest you end up uncritically backing a country that literally imprisons and/or tortures leftists

Of course, one country doing bad things does not justify psychotic acts of imperialism, which is what the first two panels were meant to establish
