Sorry -- you're not making any logical sense. You're both criticizing AND invoking authority? You're doing the same thing that the author of the article was doing -- which was attempting to preach one thing, while asserting its opposite.
You can't critique someone on the basis of their "moral certainty," while being "morally certain" about it. I deal in logic -- and there's something wrong there.
Believe me, it takes a long time -- and a lot of psychological work to be able to truly accept the freedom of men.
And each side can believe the other is wrong until the cows come home, but neither has the license to limit their Constitutional rights, as a result.
The author of the text would do well to remember that it is really big government and authoritarianism that chains people, and not the choice to pursue whatever belief system that one supports.
In my estimate, the statement is the reverse of the truth. It is errant belief systems that shackle people and, in turn, lead to the creation of big government and authoritarianism.
