No sources says "grassroots movement"  this is your WP:SYNTHESIS isn't it? A few says it is/was a movement, and some says the events were grassroot; but nearly all sources refer to MaM as an event or a protest (which took place on a certain day), and not as a "movement". We need to go with the weight of the sourcing here. My proposed wording does that, I think.  talk|contribs|
