There were left wing people going wild... The BLM riots of 2014 the BLM riots of 2016. The riots after Trump won, the riots against the Muslim travel ban, the women's march, whatever that was... All from the left.
There was the completely made up Charlottesville thing. That's the one example on the right. The trend we see is the left can riot constantly with impunity, but if there is anything on the right, however small it may be, we hear about it forever.
For instance, some idiots (Probably feds), chanted "Jews will not replace us," a travesty of course. Then we have left wing protesters calling for the destruction of Israel for the past year and nary a peep from the mainstream media. Go figure.
