If you unironically look at this image and do not understand how it is perceived as in support of the USSR, then the school system is worse off than even I realized.

Yes, you did not explicitly say it. But the natural inference is that these guys on the right, the USSR and the anarchists, are correct. To shamelessly sit there with your hands folded over like “well I’m only suggesting they’re right about this one specific thing, no one else should ever make any deeper inferences or assumptions, and it’s their fault if they do,” is either incredibly dishonest, or incredibly stupid.
