I don't see where that article provides any evidence for "The person who attacked Pelosi's husband was a leftist.", if anything it suggests the opposite.

Edit: ok, spent the few minutes tracking down an archive copy of the mentioned blogs, and ranting about "climate hysteria", "why colleges are becoming Cults", "communism is a revolution sponsored by wallstreet" and "Groomer schools" doesn't seem like usual leftist talking points.

None of those are necessarily right wing views.

Many average liberals agree with all of those. I consider liberals to be leftists, I know there is contention on that label though.

I hold a more strict view than most people on what is right wing which may be causing my different view. I consider all liberals including classical liberals to be left wing.

I would mention that "San Francisco pro-nudist activist Gypsy" isn't exactly a very right wing sort of position.

He was also a hemp jewelry maker.

At best he was in the center in common American parlance.
