Liberals and western "leftists" use the idea as a thought terminating cliche, hiding behind it to avoid recognizing when two diametrically opposed things are in fact not equally bad.
When the "lesser" evil is an openly genocidal liberal politician, they bang on and on about how it's tactical and a step in a direction and trolley problem and blah blah blah.
But when the lesser evil is a state they've been taught to villify? Oh buddy, don't you know two things can be bad at once? I hate all sides equally! (but only repeat the narratives of one).
Love the weird scale of threat depicted here.
-smol bean megacorporation
-regular bean fbi man
-Big Hacker, the big hacker lobbyist
-giant evil FOREIGNER with their evil UNIFORM and MEDALS
-ect, other guys, artist kind of blew his load drawing all those evil medals
Like the scale implies I should be most worried about the biggest guy, but I live in America. The feds are the biggest threat to me. You can tell this wasn't drawn by a leftist because...well, almost everything, but mostly because of how normal they seem to think the FBI is, and how small a deal being spied on by them apparently is compared to being spied on by someone that doesn't have the capacity to send a death squad to my apartment at any moment.
