It's one thing if they choose not to advocate carrying at protests. It's another if they actively advocate that you don't! Not sure which this is, maybe vague by design? On your other point, it's hard to imagine those drafting the BOR's contemplated no carry when protesting a tyrannical government!
I understand you're point, but due to the courts and media..... the BOR has been twisted by the current courts. One circuit says one thing, another says opposite. The supreme court is not necessarily in our favor with one variable vote deciding the outcome.
I have no issue with open/concealed carry at protests and rallies if allowed.
