The author understands their sources don't know the shooter's current thoughts on anything because he became isolated over the years. Older thoughts include:

Asked about the inscription on the bullet, the friend said: “Josh was an edgelord who wanted someone to get blamed. I think he tried his best to write something goofy … to rile people up.”

Another friend showed me a Facebook post describing how Jahn had flooded his friends’ comment sections with rape jokes — “playful shock humor,” the friend said.

More nuanced:

That said, one friend recalled that when Trump first came to power, Jahn “was not a fan” — though he had contempt for mainstream politicians in general. His friends say he had more of a libertarian bent, with one recalling an interest in the libertarian figure Ron Paul.

And finally:

“If you’re having trouble finding people besides immediate family who knew him, that’s part of the story,” one friend said. “Every mutual friend drifted away over that kind of edgelord behavior.”

So...another edgy, meme-lord gamer, spewed out from the bowels of 4chan? And they keep trying to say these guys are "leftists"? JFC. Make it make sense.

How does a dude shoot the people who ICE kidnapped and the media turns it into him attacking ICE? The agenda is so fucking obvious.

This whole case is fishy as hell, prob a false flag conspiracy, certainly not a genuine attack by someone who opposes ICE. Nobody, certainly not an edgelord, would write "anti-ice", it reeks of bullshit the same way as when republicans burn flags and graffiti their home and pin it on Antifa. And ofc nobody but a stormtrooper could go into an attack with the intent of hurting ice or liberating a camp and only shoot detainees.

He was a 4 Chan libertarian.
