There is no line, no distinction between “cancel culture” and “hold them accountable.” Pick a label. Thune is asking me to stuff a sock in my mouth.

I agree that Thune does not see this distinction. Here is my view of the difference:
Hold Accountable: you screw up, you lose your job
Cancel Culture: you screw up, you lose your entire life
