What happened yesterday suggests it was all a stitch-up, but what you do over in America is up to you. That aside, I would like to offer a constructive suggestion or two. I wasn't there, so this is the view of somebody on the outside looking in.
Based on the photos, I think some people on the March forgot about the cameras and the propaganda angle, or at least did not take it fully into account. Nobody should have spoken to or interacted with antifa in any way. One of ours was heard saying to one of theirs: "You sound like a nigger". Not good. The British National Front used to conduct relatively disciplined and dignified marches through urban areas of Britain without any trouble being caused.
I also think the use of Movement flags (swastika and others) was a mistake. Next time, instead of carrying assorted 'Movement' flags, carry the U.S. national flag. Imagine the propaganda value - a sea of U.S. flags carried by proud patriotic and nationalist men and women, a symbol of the Unity you are aiming for in that everybody unites under the patriotic flag of your nation. [A concession could be made to neo-Confederates and other Southerners who prefer the Confederate flag].
Imagine then the police even contemplating making arrests or antifa attacking you. I have no doubt they will anyway, but some of them will have reason to hesitate due how it will look on the cameras. The camera never lies. Photos of police and antifa interfering with peaceful, flag-carrying marchers would be priceless. Better still if the march is spearheaded by military veterans who are "concerned" about the "future of America", the homeland they "fought for".
