Dude, EVERYONE around the guy (his friends, his family, his trans girlfriend, everyone) said he's always on the left side when it came to politics, and one of the bullet casings had the words "Hey fascist, catch!" engraved on it. Considering the far left tries to paint all conservatives as fascists, that's also a clear sign of him being a leftist.
So just because Charlie said some "bad" stuff means it's okay to kill the guy? Does this mean I can shoot Obama because he said anyone voting against Kamala is a sexist? Or Biden because he said during his election that not voting for him makes people "not black"? Not that I would, of course. Unlike many on the left, I don't advocate for violence.
