Not Helping

"That little 'Press to Open' tab on Kraft Mac 'n' cheese boxes. That has been an effective way of opening those boxes exactly zero times."

Going Obsolete

"Planned obsolescence."

"My printer one day just up and stopped working claiming I needed to replace a part. As it turned out, that part is meant to stop working when the printer reaches 5000 pages."

"I took the part out. There’s no damage or wear on it. So I ordered a 'reset chip' that reset the page count for that part to zero. Cost me $20 vs $110 for a replacement part."

"Later on, I found a way to enable tech mode on my printer to reset the page count for any part I want. Then again, the printer is old, and the WiFi stopped working a few weeks ago, requiring me to use direct WiFi, which sucks."

Profit for Who

"For-profit prisons."

"Which leads to state prosecutors who are beholden to them. This increases the probability of being charged with a crime you didn't commit, under the plan that you're too poor to defend yourself and will plead out."

"They can't make a profit without prosecutors feeding them an ever-increasing supply of prisoners (plus parolees and probationers in "offender-funded" programs). It's a recipe for the corruption of our justice system."

"Private prisons are arguably foreign enemy assets."

Reminders of War

"Landmines. They don't just disappear once a war is over. They'll stay around to kill some kids playing. Awful things."

Bodily Weapons

"I’ll say Nerve Toxins/Chemical Weapons. I find few things worse than a weapon that literally gives you the slowest and most agonizing death possible."

- RidingRiptide

Chemical Warfare

"Chemical Warfare."

"While nukes are horrible beyond imagination, humanity learned to avoid them as a way to ensure their own survival, it's wise, but egoistical nonetheless."

"Chemical weapons on the other hand traumatized the f**k out of the survivors and the ones who called the attacks and got to see the aftermath. They were so horrible that many soldiers deserted after using them and many went mad."

"Throughout the last century, we successfully banned almost all of those: the 1925 geneva protocol, the 1980 chemical weapons convention, among others, but I'm afraid when the next generations start to forget the horrors of chemical warfare, it will resurface in the likes of what's happening with fascism."
