There is nothing liberal about this liberalism of which the author speaks. Words matter. Referring to leftist democrats as liberal is a misguided euphemism, at best. The sooner we can address it for what it is - leftist totalitarianism - the sooner and better we can push back on the tyrannical notions being pushed upon us.
Isaiah 32:5-7
5The vile person shall be no more called liberal, nor the churl said to be bountiful.
6For the vile person will speak villany, and his heart will work iniquity, to practise hypocrisy, and to utter error against the LORD, to make empty the soul of the hungry, and he will cause the drink of the thirsty to fail.
7The instruments also of the churl are evil: he deviseth wicked devices to destroy the poor with lying words, even when the needy speaketh right.
