No, it is activism. It actively draws more attention to these causes, because attention drawing things like gluing yourself to a road attract the media to report on it. Sadly, if everyone just passively protests, it is not enough anymore.

Also, gluing yourself to the road that keeps the machines contributing to global warming from running on it is kind of the point.

Being nice doesn’t work anymore. The world is actively burning. If anything, activists should be even more pissed than this, and angry at their leaders/elders for denying global warming.
