I've quoted this lyric here before, but it fits to quote it here again, in these times:
The ultimately authoritarian implications of "respectable, centrist 'liberalism'" are best described in the last verse of the Phil Ochs song "Love Me, I'm a Liberal"
Oh, sure, once,
I was young and impulsive-
I wore every conceivable pin.
Even went to socialist meetings-
Learned all the old union hymns.
Ah but I've grown older and wiser-
AND THAT'S WHY I'M turning you in!
So love me, love me, love me,
I'm a liberal!
