In social activist spheres there's always a type that's quick to come up with ideas and volunteer others but is slow to make sacrifices themselves and seldom does anything substantial.
Is there a word for this, like how the Germans have words like schadenfreude?
At a base level, all I could come up with is a "do-nothing with fantasies" but that's not quite cutting enough. "Suicide bomber recruiter" is closer, but maybe too oblique.
