Discussing this in a spanish forum right now that leans a lot to the right, so far i ve read:

• He is a troll, he does it for the memes and to make the wokes cry

• He just wanted to make a salute but has the coordination of a 30yo hikikimori so this came out insted

• He is on drugs and cant controll his body

• Its a friendly salute for his mates

• I have seen it worse for other far lefts extremist

And there is no Poe law here, these are all serious answers
