My friend always says he'll eat anything that can't take. That includes babies and retarded people. He's ok with that. *shrug*
I don't believe him.
But that could be part of a consistent belief system. Not one I endorse, but it may be consistent.
It's more of a joke than anything. But at least he has well defined boundaries!
I'd like to milk this.
Pun intended?
I don't think this grossness is logical. Milk isn't directly involved in a reproductive process: reproduction can take place without milk. It has a correlation, but given that we evolved to reproduce, many things do. Besides that, what's gross about something being involved in a reproductive process? Or something coming from the inside of another animal?
Well, milk is generated as a step in the reproductive process. The fact that it's post-birth doesn't make it any different, in my mind.
In any case, it isn't just reproductive, that's really just an example of it. I also avoid, when possible, eating other kinds of things that animals produce, like honey.
Grossness is only part of the reason, and you're right that it's somewhat arbitrary. But it works!
I still think the better reason is that animals shouldn't be treated as property/slaves. Animals work to produce something, and we take it and consume/sell it without giving the animal a share of the profits, so to speak. Animals never get to retire, spend time with their families, take a day off, go on vacation, etc. I sort of brought that up earlier, I don't really remember how much I said so sorry if I'm repeating myself.
