Depends on the venue. It was my understanding that the Auburn and Houston (wherever that last rally was where Azzmador talked to the OathKeepers) police did their jobs. Yes, we should expect police protection, we're US citizens exercising free speech peacefully.
Unfortunately, anything other than taking the beating and filing massive, city crippling lawsuits when situations like Charlottesville occurs, will not be beneficial. Retards driving cars into crowds or worse, blasting at cops or Antifa will force Trump, Sessions, and any somewhat friendly or ambivalent local govenments to come down hard on these assemblies.
Worse than that, the white public will hate us and organizations will be targeted as terrorists, funding seized, klan level fed infiltration, etc.
If white America repeatedly watches gatherings of clean cut white men getting firehosed into crowds of increasingly hostile and armed commies and freaks, then it will force them to face the necessary uncomfortable internal dilemma.
If they don't face that and don't come to the correct conclusion, then we're fucked anyway. We need a decent portion of the public to become outraged at whites being openly deprived of rights, representation, and voice.
That's not going to be accomplished by rolling into town like an armed militia. It will provoke a reponse, one that won't spur outrage and sympathy, nor a civil war. If that's what people are hoping for, they haven't thought it out fully.
