You give them to much credit.
They are too stupid to know they are supporting and regurgitating Hamas propaganda.
Their overpowering need to virtue signal and constantly trying to "out-left" each other completely clouds their ability to even acknowledge reality.
I put up a photo of a group of make-up wearing, cleavage showing young girls marching in a "pro-palestinian" protest actually carrying an Al-Qaeda flag. Two of them.
I assure you - they didn't even know what the flag was, but it had Arabic writing - so they carried it.
