I've seen various BLM, anti-racism and anti-colonialism activists in the US condoning Hamas. I was following some but that was hard to read.. would have to dig out names.
Don't know if you would call them "left" in a German context though. My experience in UK was that "left" can mean very different things, especially around racism and attitudes to violence.
Does it make sense to ask about "leftists" with a global meaning?
