IRGC, Hamas, Hizballah and maybe others are far right organizations, so I don't think this is purely left/right.
And what about signal? I am pretty sure many violent/terrorist groups use it too.
I don't have an opinion about this group, because I didn't even know it existed. But, like often with things related to the free speech, I think this topic is more complex than you make it out to be.
No one believes pro-Hamas activists in the US are voting for Trump.
Their supporters in the west form alliances with the left.
I do not think you can meaningfully fit them in a left vs right classification. There are many groups in the world that take bits from left and right. There are ethno-nationalist communists, for examlle.
