Icon Changer 

A person who loudly complains about various social/political issues, but limits their actual action to changing their facebook icon rather than actively protesting/working towards change.

If we could only get just a tenth of these icon changers to actually show up for a rally, it would be the largest America's ever seen.

JC: So you think they're going to riot?

AC: No, they won't do anything. They're just a bunch of icon changers, sitting in front of their computers all day sharing memes with their followers.
