Lot of clueless people here about political movements calling this 'useless'.
Their homework: name for me, picking from any major political movements in US history from the civil rights movement to womens' suffrage to abolitionists and more:
Name a few specific protest events that changed things. Some specific marches for civil rights, some marches for womens' suffrage, etc.
Oh, out of the many event, protests, marches, none had much specific effect?
Guess they were useless then.
Who needs democracy or the right to assemble or to petition government? It's all useless.
This event helped built the political movement. A lot of events help, a few voters each time.
