Saturated Fat Controversy

[FlatAssembler]

CO2, at appropriate concentrations, is known to produce disorientation, and then unconsciousness. Done properly, the animal doesn't even know that it's happening.

Dude, I am almost certain you are wrong about this. Look, in humans, the airway starts to hurt when the concentration of CO2 in air gets to around 5%. Yet, only when it gets to around 40% do people lose consciousness. While there is a big difference in the concentrations causing death and ones causing unconsciousness (death occurs at around 70%), the concentrations needed to cause pain are many times lower than those needed to cause unconsciousness.
And I am not going to research this much further, I have mental health issues, and reading and watching vivid descriptions of what happens in slaughterhouses certainly isn't helping.

the majority of land used to produce feed grain is not suitable for the production of alternatives -for- human consumption.

Majority? Do you have some statistics about that?

Further, if the grain were not grown to feed livestock..it simply would not be grown at all, full stop.

Less grain is produced with the same resources, therefore, grain costs less.

Finally, and this draws both topics together, criticism of a poor model is not criticism of livestock production as a whole.

Dude... this sounds just so silly, and if you don't understand why, maybe you are a lost case.
Let's try this way. You are against death penalty, right? You think that the fact that around 4% of the people on the death row are innocent is a good argument against death penalty, right? Well, what if somebody told you "Well, it doesn't have to be done that way, there are tons of ways to improve that. We don't need to abolish death penalty altogether."? You see how stupid that is? That is how you sound to me.
Or what if somebody, in a debate about whether antivirus programs are useful, said something like "Well, yes, most of the antivirus programs today have a track record of having many false positives, some of them being as destructive as the actual malware. But there are tons of ways of improving those things. That's not a good reason not to use an antivirus software."? Yes, that's how you sound.
Also, if you are asking me to count the unnecessary suffering caused by imperfect plant food production today, you ought to also look at the much greater amount of unnecessary suffering caused by the way meat is produced today.
