Yup. People have a reaaaaaalllly hard time with correlation≠causation.

Your ice cream consumption is killing people in 3rd world countries!

I have bipolar II. I think the biggest risk is that manic episodes cause temporarily impaired judgement and increased risk-taking. This can lead to people saying things they genuinely believe but would normally keep to themselves. Or, people might pick up and repeat things during manic episodes because their judgement is impaired.

If we're talking about Kanye West: Kanye was diagnosed with bipolar in 2016, but made comments about Jewish people and power as early as 2013. I think he was thinking about these ideas either early on, or before he started showing symptoms. Untreated manic episodes might have made it worse.

I appreciate your question was asked in good faith. I want to be very careful in emphasising: bipolar people are not going to become nazis. This is one very specific case. It's possible, but it just doesn't seem to happen. This is an uncomfortable time for people with bipolar, as one person's actions are contributing to the public perception of all of us.

Technically? It could warp someone's worldview so much that they could very easily fall down the hole of some conspiracy theories.

Direct line to becoming a Nazi? No. Does it help create the perfect mental conditions to be susceptible to conspiracy theories, racist tirades, xenophobia and every other ism? Yes. Will that happen to everyone who goes untreated? No. My dad has Bipolar I, currently undiagnosed because he would refuse mental treatment every single time it was brought up. He was originally a pretty easygoing, kind hearted man, but as his swings between mania and depression continued & got worse (alcohol didn’t help) he became more prone to anger, irritability, he would sleep for 1-2 hrs a night when manic, and genuinely began to believe in himself as some sort of genius artist and that the entire world had a personal vendetta against him and his attempts at success. He would rant for hours and would have to be talked down from ideas of assaulting people. His manic episodes would last months until his body couldn’t handle it anymore and then he’d be depressed, drink more, more prone to anger than even in mania, paranoid, and even more convinced the world and everyone in it was personally conspiring against him (this is the big one that leads to conspiracies and then antisemetism and racism) and that he’d fail everything he’d ever done and how none of it was even good or worth anything. The longer these swings lasted, the further he fell into the conspiracy hole. He legitimately made himself a duct taped phone case with a layer of aluminum foil in it so that “they” couldn’t track him. He wouldnt tell me who “they” were. He tried to tell me his family was in the freemasons and if I was ever in trouble ‘they’ could “fix things” for me. This is about where I cut contact with him, but my brother was younger and he still had visitation rights. He only got worse, and became sexist, transphobic, homophobic, racist, xenophobic, angry, and even more of a conspiracy theorist. He ended up abusing the fuck out of me and my brother, the latter who ended up in the psych ward because of him, and my dad harassed the nurses and social workers on the phone so badly they stopped taking his calls and told my mom he could only speak to my brother if my brother consented, which is not really a protocol they put in place for parents with custody rights, but he’s genuinely insane. Supposedly now he’s sober, but he’s funneled the manic energy into God now, which really only scares me more. Bipolar disorder can straight up destroy a person, it’s really unfortunate. The worst part is that the affected person HAS to be willing to take part in their treatment, or it won’t work. Which is why you see so many people out there who refuse to acknowledge there is any sort of problem with their behavior or refuse to get treated for their issues, because they’ve disconnected from reality to the point where they believe that the issues are not theirs but everyone elses’, or that they’re afraid to lose the energy they relied on during manic phases.

BPD is borderline personality disorder which is a different thing

BPD has nothing to do with the article or Bipolar Disorder.
