didn't read the link, but i've seen this before. i agree and disagree with it. yes, the world sucks in many ways, but is it really realistic to think that being all whiny about it serves any purpose? life is what it is. improve what you can, and enjoy what you're left with.
i think in america and possibly other western northern first world whatever you want to call it nations, we have a dominant culture that defines "realistic" in absurdly UNREALISTIC terms. i mean of course it would be equally unrealistic to deny the dark side of things, but to be as obsessed with almost only the negative, the way the dominant culture here is, i don't think its being realistic to call that realistic at all. so of course people are suicidal if they're whole perception is a denial of the reality of diversity, of reality being statistical and diverse.
I think sometimes, depressed people are just bitter and would attack anything. They attack themselves too. I knew a guy who'd bitch about EVERYTHING. I won't call him a friend because he was pure toxicity. Anyone who did well at anything he'd call "lucky". He hated his job, didn't find his wife attractive (who left him, and fucked him up even further), didn't like his life. Usually he'd just give out snide comments, but was incapable of accepting it back. He'd suck up to people for things, and bizarrely try to be the "main man". Ultimately he was just very jealous of others. One day I just said to him "You've got the life you deserve, because you can't stop being bitter, snide and jealous. Change it, or don't change it, but don't try and cover it by being a prick with everyone else". After that, friends really started having enough of him. So it was self fulfilling with him. Really horrible person. Disturbing views on paedophilia too, as an aside.
Depression provides perspective. It allows a person to discover what truly matters in life, which isn't financial success, social status, or material possessions. Having suffered from Major-Depressive Disorder for many years, as well as being homeless a few times, I've realized that the only thing that matters in life is smiles. Life is a never-ending search for smiles, and, as long as the quality of your smiles outweighs the quantity of your frowns, then you're living a good life. Fuck everything else.
You kind of make sense...until you get to the last sentence. That last senctence throws you in the loser category.
