International Peaceful Protest Day

What if we could find one day of the year, where all of us protest the change we want in the world? Where everyone fills the streets and protests what they want for the world? Would you do this if one of these was to take effect?

This would be a day for everyone who wants change to speak, and preach what they want, without being laughed at. If I enough people agree with this, I would like to get one organized. Please tell me what you think.
