It's even dumber than that.
'You can't use the same freedoms the fascists use in order to oppose the fascists which is what I'm using to oppose you right now, because that could lead to murder which the fascists have already been doing.'
It's hypocrisy2 in addition to being wrong2.
Not to beat this drum yet again but this also sounds a lot like the "I can't ignore you engaging the troll, so you have to ignore the troll" thing which I can't stand.
This fits in well with my observation that among this... type of people it's seen as better to have no standards (intellectual, moral, ethical, legal, whatever) then it is have standards and commit the Cardinal Sin of not living up to a 100% strawman, super-literal, no accounting for context version of them.
Here's how their thought process seems to works.
1. Someone tells them anything. This triggers the "How dare you tell me what to think!" subroutine. The idea that someone else has given them information they don't have offends them on a deep level and it drives them crazy. So much of their personal identity is wrapped up in "thinking for themselves" that they have started to actively rejected external information.
2. They immediately start looking for reasons the other person is a "hypocrite." And the way they do this is take the person's values, create a hyper-strawman version of them, find an incident where the person didn't live up to that version of their "standards.
For instance. AOC is actually pretty poor for a member of Congress, but she does make a halfway decent living, drives a fairly nice car, stuff like that. I mean just living in DC is goddamn expensive so I'm sure on a literal level she does throw around more money than average. But AOC is pretty far on the Left and speaks out a lot on class and wage disparity and the ultrawealthy. So the fact that AOC drives a Tesla means she's a... HYPOCRITE while a Republican Congressman worth many, many times more isn't. She is demonized for having standards. If you don't have standards you can never be a hypocrite, never be pretentious, never have to be taken down a peg, can't ever be "not as smart as you think you are" and all those other faults that these people focus on. The only sin you can commit to these people is aiming high and not making it. Wallow in the gutter and you can never let anyone down.
Now me, I operate much more on the "The pot can call the kettle black and the kettle can still be black" side of things. Hypocrisy is certainly an annoying personal trait but it doesn't override actual facts. Not matter the pot and kettles opinion of each other's blackness the RGB and Luminosity values of said pot and said kettle are verifiable facts that exist indendenatly. If I point a DataColor ColorReader at the pot and it returns an RGB value of #000000 the pot is black and the kettle's opinion is no longer needed or matters. The pot, the kettle, or anyone else can be hypocritical about the color of the pot or kettle they want, the facts don't change.
A person who says global warming is a problem and drives a nice car is STILL ******* CORRECT THAT GLOBAL WARMING IS A PROBLEM. Class Disparage isn't not a thing just because AOC doesn't live in a cardboard box and take the bus.
This is why discussions with them always have to take place in some fantasy world they are making up. They never want to discuss events as they actually happened but alternate timelines they are making up in the brain where they can control all the variables.
That's why we have a dozen threads at random point on this board where there's one person who on top of a hill going "If you ignore all the reasons I'm wrong and judge my argument solely on my alternative universe version of events then you'll have to admit I'm right."
