If you look at some of the most active groups in the pro-Palestinian left, like the PSL in the United States, you'll see that they have a very long history of praising horrific, oppressive regimes (even North Korea!) that oppose the United States, and dismissing accusations of crimes against humanity when perpetrated by those regimes. The PSL is a minuscule political party, but they're highly involved in organizing these protests.
