Many leftists are extremely idealist and get swayed by Western opinion a lot. They dont support Hamas because Hamas are not the perfect MLs freedom fighters. This is childish and just gives ammunition to the liberals to discredit Hamas’ stance. This criticism of Hamas goes against the global decolonization cause. Every time a decolonial group fights against their oppressor, they are criticized even by leftists. Is this what Lenin referred to as left-com?
It sucks that people who one thought were comrades end up doing this. Like are we even on the same team or are you just a closeted liberal? It is crazy, unscientific and unmaterialistic to not consider Palestinian material conditions, and to not consider who they made their champions for this cause, but instead to apply your idealism to the situation.
Media pressure is insane around Hamas. When you know that everyone was spoon fed narratives about them being sadistic barbarians who just want to kill all Jews it becomes very difficult to publicly support them. In some countries you could even risk have trouble with the police for "terrorism apologia" (at least that's a thing in France). So basically you only hear the people who agree with the media while the rest is shutting up because they know how much trouble they are getting into
