That is harmful bullshit for many reasons. One being that committing suicide is not about courage or conviction!!! Honestly who talks about suicide that way other than an internet troll? Because that is how you push someone over the edge.
When I was younger, and angry in random directions, I was the sort who thought that suicidal people should just go ahead and commit suicide and get it the fuck over with for the benefit of the rest of us, so that we don't have to deal with their shit. I think it's a natural consequence of growing up in a world that doesn't give a fuck about you, and does its best to show it every time you come around a corner. I grew up poor and poorly socialized, and let me tell you, that's a severely depressing state. I had basically no sense of self-worth whatsoever until my twenties. Before that, I was just randomly mean, perhaps most of the time. I didn't really give a crap about anyone else, because why bother? What a waste of energy.
Now that I'm older and hopefully wiser, I recognize that this is the attitude that's destroying our society. What's missing, first and foremost, is caring about other people. That's why so few people for example feed the homeless, even though it would cost us so very little time and money, and it's also why towns actually arrest people for doing so. Because caring is hard, and they don't want to have to do it. You make them look bad, and you make them feel bad about themselves. They know that they aren't good human beings, and they don't want to be reminded.
Of course, I'm still mostly at the talk phase. Hopefully I'll get up to the doing phase. But at least I've advanced past the shitting on everything phase. Still a bit much negativity, working on that. Let's all try to grow the fuck up and be nicer. Yeah, irony, it's a bitch, and so have I been. But maybe I know what I'm talking about, from the inside.
