Share ideas in the art of deception.

So basically,
if one is racially aware, then one is a Hitler;
if one supports public schools, then one is a Marx;
if one supports defense forces, then one is a xenophobe;
if one dislikes Gosplan, then one is a Ayn Rand;
if one supports regulated economy, then one is a commie;
etc...
