The people who have always fought to increase freedom, opportunity and rights are liberals.
And this statement all but reveals your ignorance of liberalism, and history. The liberal you are, and what the liberals in our early American history
were are light years apart. Classical liberalism maximized individual freedom, including those freedoms granted to the religious. Modern liberals like you see religious belief as an affront to the freedom of a certain segment of people, and as such it must be tempered to preserve the freedom of those few. But classical liberals worked to preserve freedom for all individuals. It didn't engage in this "selective freedom" bullshit you espouse to.
The term "liberal" has the root word "liberty" which in and of itself implies lack of restriction. The word liberalism itself also comes from the same root as liberty. It has meanings
of openness to change and a lack of restriction. Over time though, people like you have changed your ideas of what restricts and what doesn't.
