It could easily be a brigade by the left-wingers, because he is explicitly blaming them.
Daniel Perry video doesn't blame anyone. And most people, even on the left (though definitely not everyone), seem to have a normal reaction to the outcome.
I am surprised that more people don't know this type of brigading to influence public opinion. Left-wing brigades are orchestrated on private Discord servers. Smaller right-wing brigades are orchestrated on private Telegram channels.
The left-wing brigaders pretending to be right-wing CEO-killing-supporters could have gotten away with it if they had limited themselves to populist MAGA spheres.
However the Ben Shapiro fanbase are boring middle of the road pro-capitalist/neocons who would never support killing CEOs. Pretending to be his fanbase was their fatal mistake.
