alt-market.com | The definition of “extremist” is a rather ambiguous issue primarily dependent on opinion rather than fact. That is to say, it is generally the people in power and their propaganda mouthpieces that determine who is an extremist and who is not. There is no set or fair standard.
If you are a quiet and passive sort of citizen with no political deviations and no thoughts outside of what is considered “mainstream,” then you are probably considered a non-threat to the establishment. If, however, you promote an ideal that is opposed to the establishment agenda and display a potential to actually ACT to fight for that ideal, then you will eventually be labeled an extremist.
So who sets the standard for extremism in America today? The responsibility of enforcement has been undertaken by the Department of Homeland Security. But, the initial profiling of extremism and the engineering behind the farcical talking points that the DHS often uses and spreads to local law enforcement agencies is the work of the Southern Poverty Law Center.
