No one is above criticism
Now here's a really unpopular opinion on the Farms but I think it deserves saying. Mental illness does effectively take away your autonomy. Does that really excuse shit? No. But I also don't think it's really ever much of their fault or ever makes them a bad person. Now here's the real problem with saying this; on an interpersonal and personal (sjw using mental illness as a rationalization for being a shit) level, it's a worthless and sometimes harmful sentiment to have despite being, well, true.
Though SJW's may use it to justify shit in some stupid quasi-authoritarian "le selfaware" view of their behaviour, that's something still rooted in their mental hangups and is ultimately, I think, something to be somewhat sympathetic of. And it's really something that couldn't have been prevented with the huge amount of public knowledge we've gained about mental health in the past 40 years.
People seem to have this bizarre misconception in that that literally every mental illness besides schizophrenia is viewed somewhat dismissively- I'd say it's to the point that someone who has a high-paying job and mild schizophrenia is viewed to being suffering more/in less control of their life than someone with severe depression.
A person with depression who makes excuses to explain why not to eat or get out of bed or do whatever or explain why they think everyone hates them is no less fucking nuts than a person who makes excuses about why they think the president is a squirrel. The depressed person is not genuinely a lazy person and if they kill themselves, it's not selfish- that's one of the most disgustingly virtue-signal-y statements I've ever heard. If anything could excuse shitty behaviour, it's your brain being consistently and thoroughly fucked. And neither their lives falling apart or some random criticizing them on the Internet is going to break through that.
The people who don't turn into complete cunts due to their mental illness are either well-treated, a lot less severe, or, well, lucky. It takes one bad incident to send someone into a spiral. "Willpower" becomes a lot less concrete once you realize there's a magical chemical connected to it though that's ultimately an uncomfortable and near hollow truth you should never fully come to terms with.
TL;DR: So what are you supposed to get from this? Don't criticize mentally ill people for their behaviour? No, well, because on some level, it's just. Though in some way, you should realize it's a vain sentiment to express and it can, at most, encourage them to see a doctor.And I think there should be some level of sympathy maintained for someone with mental illness at all times because it essentially takes root within their personalities and regularly eats away at their ambition, cognition, and lives.
Something you should really get from this is to not chastise a mentally ill person for paragraphs on end or even take cows' personal lives at all seriously while on the Farms because that's just fucking stupid. This is supposed to be a funny website.
