jackmarshallize 

(verb) to write, pontificate or act in such a manner that resembles unconscionable, sadomoralistic douchebaggerry of the very highest order.

Jack Marshall is a self-proclaimed champion of ethics, but he is actually just a lawyer who is invariably very rude, dismissive and intimidating.

In attempting to defend the indefensible (most often his beloved policy of drug prohibition) he does so mainly from the power of his own extreme prejudicial convictions – by blatantly ignoring fact and historical precedent he has achieved the highest form of cognitive dissonance and suffocating bigotry.

Mr Marshall’s convictions are most definitely not based upon the ethics he purports to champion, but are the ‘ethics’ of utter malice towards all who dare to disagree with his particular form of stifling, authoritarian hypocrisy.
Usage: “Do you honestly believe you can just march in here and simply jackmarshallize us?

jackshart
