In the beginning, there were a few diehards, committed to raising awareness of their vision of the perceived injustices being perpetrated by an overbearing government. They believed that speaking up and taking action was the only way to draw attention to the problems they saw.
Their main weapon was to gain notice, but they needed an outlet to gain the attention. So staging rallies and protests, all under their recognized 1st Amendment right to “assembly and petition” their government, was at first small. But as time marched on, so did their numbers and strength.
