There are far left extremists that are violent here. There is a big difference between the far right who take some weird pride in their violence and wear their prison time as a badge of honor. When left extremist are arrested and their names are published after being sentenced they often get really pissed off that they have been outed and it will ruin their ability to get meaniful employment. Both sides are strange as fuck that they feel persecuted after destroying shit, harassing people, and injuring people. Both sides think they are justified in their transgressions. We have a political and justice system to solve these issues, nobody needs to harassed, injured, and rarely killed so they feel their political voice is being heard. Luckily both the radical left and radical right are pretty low number groups. Most of us are far more likely to be injured in a traffic accident than to come in contact with these nutters.
