I'm confused. Are you saying he didn't kill anyone?
No, my point is that for the bloodthirsty, inbred, hillbilly hick of progressive fever dreams, he waited a remarkably long time before defending himself. Rittenhouse didn't defend himself until he was literally seconds from being killed. His first response to the four people trying to ambush and kill him wasn't "Alright, my dream has come true, I get to kill people" and start blasting away, it was to run away from the people attempting to murder him towards the police line.
The irony is, for all the Sturm und Drang of people being outraged because some BLM members were prevented from killing someone they wanted dead, this was a bog standard case of self-defense. Rittenhouse's actions would have been ruled self-defense even in progressive states that have a "duty to retreat" clause before being allowed to defend yourself because he tried to run away after the initial ambush. It was only after being cut off from safety and knocked to the ground that he started to defend himself rather than run away, which is odd behavior if the whole reason he was there was to kill people.
And of course, this completely ignores to culpability of the people attempting to kill Rittenhouse. If they had simply returned to setting things on fire and destroying property after the initial assault on Rittenhouse, nothing further would have happened. It had been made clear that section of town was being abandoned to the tender mercies of BLM, so they had nothing to fear from the police. But they didn't just want Rittenhouse to stop putting out the fires they had been setting, they wanted him dead. As Rosenbaum put it earlier that night, "If I catch any of you [people trying to protect the town] alone, I'll kill you". Apparently, he recruited some other people to carry out his threat.
