I agree that the police reform message is often lost, but you're mistaking the views of a fringe left for those of the majority of people protesting police brutality, who are just normal folks who are tired of (for decades) watching the police menacing society rather than protecting it. Live in another country for a few years to understand that a militarized police force is neither necessary nor supportive of the police' own motto: to serve and to protect; not to bully, beat up, pepper spray, hit with batons, shoot with rubber bullets or water cannon, suffocate, nor shoot in the back. The vast majority of people protesting are simply against police violence. You?
Fascism is right wing, by definition and historically. If the term has any meaning. If we can't agree that fascism is a right wing phenomenon then there's little point in further discussion.
Antifa is (according to the Oxford English Dictionary, hardly a radical organization) "a political protest movement comprising autonomous groups affiliated by their militant opposition to fascism and other forms of extreme right-wing ideology." So being opposed to fascism would put them on the left. I'm assuming we agree on that.
So unless you are arguing that any violence by anybody must be fascist, we seem to agree. I'm against political violence by the left or the right, or the police. You?
