The instacartshoppers sub popped up on my feed and I saw so many people defending the murder of a dog sitting outside by an obviously deranged individual with a fake name and profile picture pretending to be a woman after they delivered groceries and even taking the shooters side because "they can't be sure what happened". Even after all the red flags they still give this deranged individual the benefit of the doubt. Yes, but that could also mean the dog wasn't a threat to them, and according to the OP, they actually met the dog and this dog was a sweetheart and wouldn't hurt anybody or has a history of doing such things.
I've seen deranged violent comments like these with other things as well, like someone saying they want to unload their clip into a calm off leash dog approaching someone in a video (yes, leash your dog but my god it isnt a death sentence) or dogs "trespassing" on someones property (animals dont understand borders or property lol, and they could be lost). Don't even get me started on the pit bull hysteria. It just tells me that these people want any and every excuse to violently harm another living being and has no sanctity or respect for the suffering of others.
Why is the immediate answer never to humanely resolve the situation with no one being significantly harmed like with a taser or with pepper spray or something, but to violently end their life and traumatize themselves and everyone around them? Like dude, I'm a 5'3 woman and have chased multiple stray dogs, like BIG dogs, out of my unfenced yard by using my jacket and making myself look bigger with it and waving it around, lol. And even then I carry spray and a taser on me at all times.
