Again, I am confused about the point you are making. I don't think anybody disagrees that fascists (actual fascists) and lunatics that commit these murders should be buried under the prison.
The author highlighted that an antifa member shot and killed somebody. Instead of speaking out and decrying such an action, the point is sort of passed over and refocused on right wingers.
Does this mean its ok for antifa members to now kill people they deem fascists? To beat them? to assault them? This isn't an either or question. Both sides can be wrong at the same time.
