In the article, Walter Lippmann's argument is basically questioning whether political freedom is an ideal or right. He talks about how everyone pursues it as a right and tolerates other men's opinions. The author brought in an example to support his question with Voltaire's say, "I wholly disapprove of what you say, but will defend to the death your right to say it". The writer strongly contradicts how men will not defend to the death the rights of other men like Voltaire. However the two different perspectives of these two helps his argument as he also says men will put an end to those other men only if possible and to an extent.
On lines 42-45, the writer compares how we tolerate the freedom of our opponents as we tolerate a crying baby
