TGT leans towards individual liberty, which is classically liberal. The modern use of the word is a perversion from the progressives and marxists who want to confuse language so that they can manipulate people on emotion instead of reason.
That statement actually shows deep insight of the philosophy of politics.
Here’s a great traditional philosophy read that liberalism = liberty and has been corrupted by modern politicians to mean a broader theory of ethics, value and society.
