Your argument is literally identical, logically, to “she was asking for it by being dressed so provocatively”.
It’s literally identical, logically, to “She dressed provocatively, but was carrying a revolver, and walked into a bad part of town waiting for someone to come onto her so she could shoot them.” In which case I’d be making the same argument.
Look, I want to be clear: I’m not saying he deserved to get attacked. But I also don’t believe for a second that he traveled that far, to a protest where any logical person could have guessed they’d be seen as an aggressor, and walked around for as long as he did, and wasn’t hoping he’d draw some aggression so he could “defend himself”. It’s unfortunate that it happened, and I do believe he was defending himself, but I also fully believe that it went down exactly like he was hoping it would.
The fact that he’s been riding out his celebrity status among the far right since then, I feel, supports that theory.
He can be “not guilty” and still be a piece of shit.
