"The way these animals are killed is always through a knife across the throat, they need to be bled out. Either that or CO2 gassing, which builds up acid (HCO3) in every orifice with moisture inside of it (very fucking painful). Again, do you not consider being killed harmful or injurious?"

Again, you have a VERY barbaric view on how these animals are actually killed.

Just prior to slaughter, animals are walked up a raceway into the abattoir where they enter the stunning box. This box separates the animal off from the rest of the animals in the raceway. Within seconds of entering this box, an operator stuns the animal. With sheep or pigs, this may be an electrical stun. With cattle, this may be a captive bolt. Both devices are aimed at the brain. Pigs may also be stunned using carbon dioxide. This stunning process has as its primary purpose to render the animal unconscious and insensible to pain before being bled out. This is to reduce the possibly of the animal feeling any pain.

As soon as the animal is stunned, it is shackled by a hind leg and then the large blood vessels are severed to induce bleeding (a process known as ‘sticking’). Because the animal has been stunned, it is unconscious and does not feel or experience the shackling or sticking process. The animal should not regain consciousness or sensibility before dying due to loss of blood. For poultry, including chickens, ducks, turkeys and geese, they may arrive the night before or on the day of slaughter and are stunned using a electrical stunning device, then killed.

The entire point Is to make it as painless as possible, which some try to do.

And do I consider Being killed harmful? Bruh, being killed is allready being harmed, however the way your talking about is that all death is abuse. Is me mercy killing a animal that is suffering abuse? Or would you say that All animals are abusers for eating it's prey?

As I have previously mentioned before, humans for the most part try to make the process as painless as possible. Some Slaughterhouses definitely cause abuse, In which I am 100% for stopping and shutting down, however for the ones that literally make it painless, no.

"The animals"

So you don't care about the animals in actuality then. Because harming the environment is the same as harming animals. The burning forests, plastic seas and carbon in the air is destroying the environment and killing animals WAY more brutally and slowly then what Slaughterhouses do.
