Serious Question: Do these quotes just result from political partisanship or is this poster truly disturbed?

You're right, of course, that behavior like this is rampant on the left. If there's one thing that makes this poster stand out from the others on this board, however, it's that he seems to more erratically wear his heart on his sleeve, as opposed to just the usual combination of mindlessness, canned talking points, and hatred. He even mixes in bizarre personal anecdotes that are often dubious but detailed. As NormaAndNorman said, it really is as if he's writing in a diary. It's a window into a dark place.

I know. The sock conspiracy rabbit hole stuff is insane and ignores all actual evidence. It's hilarious to watch them spin this crap up though as they try to rationalize large numbers of people actually disagreeing with them, let alone routinely stomping them in debates. Surely it would be more comforting if we can all be diminished into a single enemy they can focus their blame on.

As for the mystery "diary" poster, the op is just the tip of the iceberg. You need a hazmat suit to trudge through his posting history. I didn't even use most of the best (or worst) stuff.

Delusions involving the outside world, other people, and himself (the "poster of quality" with an impeccable "reputation", unlike everyone else). Fantasizing about getting to celebrate other people dying. Extreme paranoia. Conspiratorial thinking. Spewing hateful vitriol at children. Frequent wording like "fear", "frustration", "pissed off" to describe his own state. Telling admissions like this...

"To be honest, I'm STILL in disbelief that Donald Trump is actually a president. I can't reconcile that in my mind."

...that show his mind is struggling to grasp reality. In other posts he talks about literally having headaches caused by Trump and his supporters existing. Countless lines of drivel like this...

"Jesus. it's like Trump is transforming ICE into some sort of pseudo-Nazi regime."

"This is Russia, right? NAZI Germany? Sure feels like it with Donald and his dictatorial policies."

...that shows not just ignorance, but a brutally warped worldview lacking any stable sense of perspective.

He admits he never even followed politics until Trump's election pulled him in for some reason. He can't rationally articulate why that bothered him so much but he's fixated on this President as his entire motive for posting and spewing what he does.

Then there are his frequent meltdowns, long meandering rants that run an emotional roller coaster of despair, anger, and back to despair within a single post. I’m not a psychiatric professional but it seems to me there are red flags all over the place.

Thanks. He is claiming to obsessively follow your posting habits though, lol, as you can see. He's talked about interacting with you in the distant past so you've likely had him blocked for a long time.

What if it helps save a life?

Well ideally when someone makes a bold accusation they back it up with with facts and evidence. As the OP clearly did.

No surprise this would catch some off guard as the backing of bold accusations with any facts has become foreign to the communist run Democrat media/party.

Just a few examples: the original October surprise, when In 1981 Democrats accused VP Bush of flying to Iran in an SR-71 to have them hold the hostages taken under Democrat President Carter until after Reagan was nominated.

Then there was the Anita Hill accusations against Supreme Court nominee Clarance Thomas with zero evidence.

Then there was the communist run Democrat media/party calling the ‘92 recession the worst economy since the depression.

Then there was 1st lady Hillary Clinton calling the Monica Lewinski scandal a right wing conspiracy.

Then enter the 2000s when the communist run Democrat party/media accused Bush of letting 911 happen. And making hurricane Katrina happen.

And now under Trump we have the Russian collusion hoax that has still yet to produce a single piece of evidence.

And the accusations against Supreme Court Justice Kavenau.

And the latest, the so-called whistle blower accusations who never even heard the phone call which we have the transcript for.

Yep. See that’s how you have to work when you have no substance. That’s how the communist run Democrat media/party works. And their brainless lemmings fall for it every time without care of the truth.

Maybe, maybe not, but we're not on the Breitbart comment section. These quotes all come from a regular poster here.

For what it's worth I don't recall seeing conservatives, then or now, call for humanity's extinction, fantasize about celebrating their political opponents' deaths, call children "pieces of shit", or exhibit the combination of other twisted patterns shown in the op. I'm not saying it's never happened, but that kind of behavior in general is way more common among leftists, and this guy seems particularly disturbed.

What do you expect when you have lead news anchors from the communist run Democrat party media calling Trump Hitler at his inauguration. The obsessive hate and ignorance isn’t just from crazies on some movie board. It comes from their communist leadership in media and party.

Communist professors lead protests, incite violence, and fight to ban free speech at institutions of so-called higher education. They attack the very foundation that gives them the privilege to snivel.

The left can’t think for itself. They don’t address evidence and formulate an opinion. It’s well beyond their mental capacity. They respond to instructions, regurgitate what they’re told, and screeee. And they do it proudly.

I think anyone who has spent any fair amount of time here knows who he is.
