Yes, yes, I know, everything is a slippery slope towards the Orwellian dystopian nightmare and the boot stomping on our heads forever.
Pseudointellectual quips like that have become such trite and banal cliches at this point there's nothing left to do but laugh at them. Throw the one by Voltaire onto the pile too, or the one about trading security for liberty.
You are using a bunch of emotional non-arguments like "trite and banal" while not addressing the validity of these slippery slopes, on top of lacking history knowledge (for example check how blanket arrests for suspected FETO supporters extended to arresting opposition under the same name in Turkey). Makes me think your reply is more about helping yourself feel safe and secure rather than arguing.
