Of course, they are EXACTLY alike, <sarcasm> because umm ummm they both have two arms, two legs and a nose. Then again you consider consent and submission the same thing so I can kind of see how you would mistake an 1800s abolitionist and freedom advocate for a 20th century douche bag with the world's worst hair.
spooner and trump sound very much alike
both are media whores who love to see their names in print, spooner "self published" thusans of shitty pamphlets, trump hosts "reality" tv shows
both had dreams of becoming financial market makers, spooner wanted to be the Postmaster Admiral (general was already taken, and navy uniforms are so spiffy) and trump wanted to be the lord of all lands in new york and new jersey
spooner declared himself to be a lawyer by the power of his karl marx beard, trump declared himself a force in politics through the power of his bad rug
both went broke and had to run to daddy for a bailout
both pretend their failures are due to government oppression of their genius
niether one is capable of making a cogent statement
both are slaves to their egos
niether one is fit to lick thomas jeffersons boots
