Nah - gotta look at the negative space.
If he was a Trump supporter that’d already be out there.
They’re trying the white supremacist angle but it’s not that either because his writings (as few as I’ve actually seen) were, like the shooter in New Zealand, inarguably leftist. So they won’t point that out either.
He’s antifa and anti trump - so the answer is “we just don’t know”
