I disagree. Be there, but just Witness. Do not mock them, or react to non-criminal behavior. Just be there and ignore them.
They WANT a reaction. If we just sit there and eat our chicken sandwiches, then they are defeated in their mission.
The presence of conservatives will also serve to deter any illegal acts like vandalism.
I see your point but what it leaves out of the equation is a deliberate provocation on their part to get a desired ‘reaction’ to film or document. You can’t tell me that if one of their vile comrades spits on a patron or some other vile act that our side is just going to sit there and take it. I just see nothing but trouble but hopefully I am wrong. We forget that they are not playing fair. They are jackbooted thugs.
