How do you know he didn't? I'm always one of the first to stand up for men when they are abused by women, but we don't know even half the story here. All we have is an out of context video that paints Solange as the aggressor. It's probably best not to jump to conclusions on either side tbh.
We can only base it on this video and he didn't and if he did it before the video, then why not do it again when he was being attacked? He obviously said something that angered her so much.
