Just to be clear: Are you asserting that the fact people are building/taking into account logistics to protest for the long haul with regards to something they vehemently disagree with detracts from the legitimacy of the act of protesting?
If so, wow. That's low-key\backhand authoritarian to a T; defining legitimate protest as something that isn't in the grand scheme of things effective at disrupting something enough people disagree with, and anything that does make a dent either terrorism or something else.
