Defenestrator gives the following description:
The defenestrator is Philly's sporadic newspaper for resistance, creative revolution, and action. To defenestrate Power means total refusal of its tools and tentacles. Like the Hussites who had their oppressors thrown down from the Prague castle into the angry mob below, the defenestrator wrestles power and privilege from its highest and most protected strongholds and casts the beast out of the window and down into the angry hands of the people.
The defenestrator doesn't adhere to a strictly defined ideology, but we generally derive our ideas from an anarchist or autonomist tradition, which proposes a revolutionary transformation of society, the abolition of property and of all hierarchies and coercive power.
