What makes you think these were from far-left extremism? What groups or ideology did they profess to be a part of?
You don't need to be associated with a group to be an individual extremist deciding to advance a movement. The shooter's photographed doing a black power salute. The black power movement isn't right wing.

While there may certainly be more extremists on the right the idea that someone on the left can't be an extremist, or that there are no leftist extremists, doesn't make much sense.
Well of course it doesn't, which is why nobody was saying that. There's been plenty of horrific deadly left wing violence historically, both in the US and other countries. It's just that in the last few decades and limited to the US, there has been little to no deadly left wing violence, a time period which has seen quite a lot of deadly right wing violence.
But also, yes, I think it's not unreasonable to expect that people might show more outrage for murders than for property damage, even if they disagree with both.
I never mentioned property damage. Antifa's violence isn't "property damage". This is the kind of thing I'm talking about: bad faith straw manning to justify ignoring violence by leftists.
The dataset that I mention above doesn't contain any references to antifa. This is probably because 'antifa' isn't a specific group, but an umbrella term for a number of groups, some of which are entirely nonviolent or target only property.

This is pretty unfair. I'm not in a position to do anything about any particular act of violence, but there's a strong chance that if you suggest a concrete example to me I'll state that I disagree with it. For example, I don't believe that you should punch people you disagree with in the face, regardless of whether they are fascists or not.
You should not be surprised however, that people are more aware of violence resulting in fatalities and more vocal in their condemnation of it than other violence (even other violence that they also disagree with).
