"Progressivism" seeks to equalize all through government action, such as wealth redistribution, and "social justice." But this means that certain individuals must give up their rights in subordination to others in a group.
"Both freedom and rights are futile without the principle of equality of rights. Though people possess a vast array of individual differences, all members of a free society should be treated equally in two respects: in the equality of their individual rights, and in their equality of treatment before the law. Freedom cannot exist for those whose rights are subordinated to the rights or objectives of others."

Leftists hide there agenda and attempt to make it palatable through inocuous terms like "social justice," "fairness," and "for the common good." But a look at what these terms actually mean for a freedom loving people is chilling.
"Though the Progressive version of equality is presented to society as "fairness," it paradoxically requires unequal treatment by the force of government to subordinate the rights of some to the dictates of others in order to facilitate the latter's aims. The objective rule of law is bent to accommodate preferential treatment of chosen groups who, in turn, reward their government benefactors with electoral support."
Thus, we can understand the actions of Eric Holder, who chooses which laws to defend, and whom to prosecute or not under the law, depending on which group they belong to in society.
