From the murderer's text messages:

> Roommate: Why?

> Robinson: Why did I do it?

> Roommate: Yeah

> Robinson: I had enough of his hatred. Some hate can't be negotiated out.

Besides everyone around him testifying that he'd been left-wing ever since dropping out of college, his admission that he found Charlie's relatively moderate speech "hateful" strongly suggests the murderer was quite far to the left.

Ridiculous conclusion. Empathetic Right Wing people can also have found his speech hateful. Have you actually listened to any of it?
