The point is that it did nothing.

A single day protest does nothing

A single day holding placards does nothing.

You need to be out there having an 8 million protesters protest for a month. THAT will change things. Every day, go out again. And again. And again. Police will be brought in by day 3, and you will need to move and run for your own protection, but you keep on coming.

That is the kind of thing that will make changes. This did nothing
