There is absolutely such a thing as too much liberal activism, as we know from eight years of Obama’s open borders, Obamacare, Gay marriage, LGBT restrooms, a nuke deal with Iran, etc. In the last eight years, Obama’s actions and policies have broken duly passed laws and were in violation of the constitution just as they were contrary to polite, appropriate behavior among the American population.
But along the same line of thought that asserts one cannot have too much liberty and freedom, I don’t think America can have too much conservatism because real conservatives obey the constitution, they abide by the laws, and they insist that all Americans have the same rights and liberties (and the pursuit of happiness) that they, the conservatives, have and enjoy.
One will look a long way among the most conservative cities in America to find a murder rate even approaching that of the very liberal, and sanctuary-providing, Chicago. And looking further afield elsewhere in the world, the most left-leaning nations (Cuba, North Korea) are the most oppressive. It’s too bad American leftists don’t have the ability to critically examine their opinions and policies or they would understand the blessing America provides to the poorest and most wealthy among us.
