The reason why is the ideological left/right debate was never settled. The right thought with the collapse of communism they won but the left just regrouped and went underground knowing they couldn't win the ideological debate so they focused on language policing and moving in immigrants who would vote for their policies because they don't know no better.
The whole system is screwed because the right have finally woke up to what is going on and both are playing for keeps.
Whilst your energy and other peoples energy is focused on arguments such as the above the overall ridiculous circus to which all contribute just rolls on. It's depressing the amount of brainpower and hours of study and debate that reasonably to highly intelligent people put in to just prove the other side wrong. Clowns one and all. Scarily stupid ones.
