Honestly? I think that’s a fair assessment. I was always told growing up “don’t go looking for trouble, because people who do usually end up finding it.”
I think it’s an extreme version of the Rule of Stupids: Don’t go to stupid places with stupid people at stupid times to do stupid things.
As well-intentioned as I really believe Rittenhouse was, traveling to Kenosha to walk the city streets after a curfew during a riot while openly carrying a rifle rather flagrantly violated each element of the Rule, regardless of any good deeds he did while there.
