Stating that the founding fathers were classically liberal does not mean that they somehow endorse modern "progressive" liberalism.
That's revisionist BS and a disingenuous attempt to equate the two at best. The position of the founding fathers most closely resembles the views of today's conservatives (generally speaking, ofc). They set up the framework of the U.S. Government to ensure that it would not overly control The People. Over the course of time, however, the size, control, influence, and power of the federal government has grown beyond their wildest expectations (despite their very clear and explicit admonition against such centralization of power).
They understood that the government existed to protect what it could not intrinsically grant. "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." The government doesn't give us those rights, our Creator does. The government serves the people to protect those rights.
The point is that the purpose of the government for progressive liberals is drastically different compared against the role that the founding fathers envisioned for it. Today's liberals want to empower the government to control all areas of our lives according to their ideologies. People not aligned with their ideology are purged out by attrition until ONLY their ideology is upheld by all. BUT THAT DYNAMIC inherently limits our GOD-given freedoms and personal choices. To them freedom isn't as important as their need for control because they understand that a citizenry empowered with autonomous freedom deflates their ultimate quest for power. Ironically enough liberalism's view of personal accountability is not critically important - though to conservatives personal accountability goes hand-in-hand with the concept of freedom. As John Adams phrased it, "Our Cons ution was made only for a moral and religious people. It is wholly inadequate to the government of any other."
Have you even studied U.S. History?
