I'm struggling to understand what Elon Musk's crime actually is? Being successful? Having influence on the internet? Not following the narrow railroad tracks of a particular ideology?

I don’t think they were stating it as in they had examples, they were extrapolating from other left leaning activities like BLM vs Insurrection. Similar aggressive approaches but only insurrection gets attention as bad.

BLM protested police brutality. Jan 6th wanted to stop / prevent a democratic election process. Seems like different things to me.

> Jan 6th wanted to stop / prevent a democratic election process.

And possibly abduct or murder congresspeople (thinking of the guy with clearly visible tie wrap restraints, or the republican that was telling where to find democrat members of congress)

And the violent parts of both were pretty roundly condemned?

These two are not comparable; you're trying to push an indefensible equivalence.
