“The essence of Liberalism is negotiation, a cautious half measure, in the hope that the definitive dispute, the decisive bloody battle, can be transformed into a parliamentary debate and permit the decision to be suspended forever in an everlasting discussion.” (Carl Schmitt)

It would seem then, that Liberalism is both aggressive, and timid. It is jealous in its pursuit of power, but it is afraid of being too aggressive, thus it is also timid in the way that it pursues power.

Thus Liberalism is (at least in part) driven by fear, a fear which infects the liberal man. It declares both that man has rights, but that he must always be on guard against the “other” who may come to take that which is his.

It’s this attempt to combine perpetual strife, with your neighbor (in the broad sense) through “competition”and the promise of inevitable progress, and happiness that engenders fear in the adherent to this ideology

Look around at the state of affairs today, and you will clearly see the manifest failure of Liberalism as an ideology. The behaviors present in the members of society are clear expressions of paranoia. We are afraid that everyone is coming to take our land, money, or “rights.”

Addendum I: after a small conversation, and with the advice of @MScarince I would replace the term Liberalism, with Reductionist Progressivism.
