Was gonna make a blizzard joke here, but this person is so intellectual that they wouldn't get the low-grade humor, or how milk production before markets only works if everyone works a single farm, and cannot work if the population is scaled up.

Milk is the best part of the woman

You: hates milke because it is unethical

Me: hates milk because it is fucking disgusting.

We are not the same

Transcribing the conversation here:

Recessa, ↑4 ↓1: That's completely idiotic, milk exist because there's demand for it.

commie, ↑1 ↓4: I think you understand that milk is produced as part of the mammalian reproductive cycle. can you describe the causal steps between demanding milk and it's production?

friendlymessage, ↑3 ↓2: Do you think dairy cattle just randomly spawns on the planetary surface?

commie, ↑1 ↓3: do you think there's a direct causal link between drinking milk and more being produced?

friendlymessage, ↑3: Are you fucking with me?

commie, ↑2 ↓3: no. I'm trying to illustrate that markets are not governed by natural law; they are populated by irrational actors.

friendlymessage, ↑2 ↓1: Yeah, but they're not as irrational as you are and producing milk costs money. If there's no market, they will stop because they are not fuckin lunatics and they don't have infinite resources

commie, ↑2 ↓2: milk was farmed before markets existed. there is no reason to believe that will ever stop.

friendlymessage, ↑3 ↓1: That... must be the dumbest discussion I've had in a while. Please read through your comments tomorrow when you're sober

commie, ↑1 ↓1: I've been sober all day.

friendlymessage, ↑1: Okay, whatever you say

commie, ↑1 ↓2: everything I've said is true. you're objecting to reality, and being pretty shitty about it to me.

friendlymessage, ↑2: No, you're just making a no sensical argument at all. Milk was farmed from dairy cattle because it was consumed by humans. It's simple supply and demand. There is no rational argument at all that if mankind stopped consuming milk, it would still be farmed. Why would any farmer go through the effort to upkeep cows and keep them impregnanted to make them produce milk if they cannot trade it or won't consume it? Yes, humans have free will but they won't produce stuff with very high effort just for fun. Except maybe very sick minds that just enjoy animal cruelty. And you won't elaborate what your actual point is anyway.

Also, not that it matters, but you're arguing that dairy farming existed before the market is simply wrong. There has been trade between human civilizations long before we started domesticating animals.

this is 1/100th of the insanity that happened on the reddit sub r/milk
I'm pretty sure there was a riot because the mods said almond milk was allowed or something like that

I would just like to bring up that most equestrians don't farm their horses milk. Without demand it would probably be similar

Ah yeah, I've had an interaction with that anti-vegan user before, and let me tell ya, if you want to speedrun vegan bingo... ideal discussion partner right there.
