Leftist Dogma and its Derangements
The left loses every time on philosophical principles and on historical and economic facts. This is why they usually offer nothing more than imaginative and deranged expressions of antipathy towards conservatism. They can't disprove that Man has unalienable rights to liberty and property. They can't disprove that big government devolves into wasteful kleptocratic bureaucracy. They can't disprove that some ways of life are better and others worse. Because these things are demonstrably true. And yet the falsehood of these truisms is the core of leftist dogma.
If the core of your dogma were demonstrably false and yet you were unfailingly committed to it, you would be deranged, too.
