Is There Any Point to Protesting?
It depends on how you protest and who does the protesting. The lame-ass protests you see happening in most of the United States are ineffectual because they don't threaten those in power, because they're either holiday-looking marches or they're staged by students/young people, who are easy to ignore.The only way you can change something by protesting is by projecting power. You do that either by the way you do the protesting, i.e. by actively engaging the police forces in trying to reach the seats of power (Parliament, Government's buildings) or by taking up in the streets the people who have the most power come election day, i.e. lots and lots of middle class people.Movements like BLM  are ineffectual when protesting because they do neither of the 2 things I mentioned above: they don't actively engage the powers in Washington and they are not joined by lots and lots of middle class people. As such, they'll remain ineffectual as long as nothing changes.Source: me, a guy living in Eastern Europe who has grown-up by watching protests toppling Governments and who has actively joined those kind of protests once I grew up.
