The problem is that you are associating something that is almost completely non-liberal with some sort of pejoritave of the word "liberal".
A liberal person will never impose his \ her will upon anybody else. The very essence of liberalism (IMO) can be summed up by Messrs Jefferson & Locke:
"We hold these truths to be self-evident, that all men are created equal, and are endowed by their creator with certain unalienable rights, that among these are life, liberty, and the pursuit of happiness."
Somewhere in the passage of time some political activists have tried to redefine the word "liberal", in such a way that what is called a "liberal" in contempary discourse is, as far as I can see, most closely approximated by the word "Marxist". Now, as per Bakunin (he's my argument from authority

):
"They [the Marxists] maintain that only a dictatorship—their dictatorship, of course—can create the will of the people, while our answer to this is: No dictatorship can have any other aim but that of self-perpetuation, and it can beget only slavery in the people tolerating it; freedom can be created only by freedom, that is, by a universal rebellion on the part of the people and free organization of the toiling masses from the bottom up."
In other words, you are arguing against the wrong "threat" here. Your "threat" is Marxism - not liberalism.
