If he yells "free Palestine" while doing it, that means he's associating himself with others who support a free Palestine. And that means other people won't want to associate themselves with them.
I feel like this is very obvious but people seem unwilling to acknowledge it. Because they view this guy as on their side. But he's on the side of narcissists, not people who are effective at saving Palestinian lives. He didn't think at all about whether this will save or cost Palestinian lives.
I feel like the free Palestine movement in particular needs to understand this: if you want to save Palestinian lives, you need to convince people. And you don't convince people by shooting at them, or by justifying people who shoot at them. Think about it: do you see Coke murdering Pepsi supporters as part of a marketing campaign? No. Because the people they hire for marketing are paid a lot of money to actually succeed. Instead they associate coke with positive things, by bringing in celebrities, and generally portraying coke drinkers as cool people.
You should try being more like coke. Sorry if this sounds belittling, but I feel like it needs to be said because free Palestine people seem to think the best strategy is to piss off the people you're trying to convince. And that has never worked once in the history of mankind.
