I agree that, ignoring the other possible factors, saying "I should eat chocolate ice cream," means I choose to do so because of taste. I applied my taste to my choice. But that's still an application of a taste to a choice and not the experience of taste itself, so that (1) and (2) are not identical things being expressed. And (3) is still different because one is applying their taste to another person's choice to form a judgment.

No there isn't. Again, we've been through this, earlier you've affirmed that it made no sense to say "our personal preferences are objectively wrong or right when talking about a manner different from factual statements about those personal preferences" here.
The above "should" is not about something being objectively wrong or right. If I say that Johnny should eat pistach*-io ice cream, I'm not saying that it is a right action for everyone to undertake. I'm saying that Johnny should eat the flavor of ice cream that he likes because he subjectively likes it, rather than the flavor I like and he hates.

Sure, that's how you put it into a deductively valid form, but I didn't mean to imply that I thought it logically invalid. The same critique remains, but is now just phrased as: why do you think that missing premise is true?
I think that premise is false. If he is talking about his own belief about the shape of the Earth, then, yes, he can only appeal to his own subjective experience. If he is talking about another person's belief about the shape of the Earth, then he can either:
1. Appeal to his own subjective experience (i.e., apply his personal hallucination/experience to judge the actions of others).
2. Appeal to shape being a subjective feature of the Earth (ignoring his own subjective experience of that shape) and form a belief based on that general claim.
Bust Nak wrote: ↑Tue Sep 22, 2020 5:22 amI explained it here. In short, there are two main categories of reasoning to believe something - because of objective reasons - reality outside of one's self, i.e. (A) and (B) type that you brought up last week; or because of subjective reasons - (C) own subjective experience of reality. Given (2) x is subjective, we can rule objective reasons out, leaving the only viable option (C).
But under that categorization, saying that ice cream taste is a subjective feature of reality is objectivism.
Bust Nak wrote: ↑Tue Sep 22, 2020 5:22 am(3) should not be about how one feels at all if it's a continuation from the objectivism/non-objectivism issue, but about what one makes of something being a subjective fact of reality. I think it's:
(3) Johnny thinks that since the shape of the Earth is subjective, he can say that people who disagree with him on the shape of the Earth are correct as well as him.
Why not make this (4) and we can have both. Lets have both.
We can have both as possibilities, but the original (3) is false. When faced with the belief that shape is a subjective feature of reality, it is not true that one can only share their own subjective experience. One can do that (i.e., do (1)), but he can also conclude that everyone has their own hallucinations and, applying this belief, either choose to judge others according to (a) his own hallucination, (b) their own hallucinations, or (c) make no judgment at all. Possibly something else, but I've little time to think that through more for the moment.

That's not me applying my hallucination, but having the hallucination. I apply that hallucination to myself and choose to ban Johnny from abusing children. Your suggestion that this somehow amounts to applying it to Johnny is inconsistent with what you said here.
What do you mean by "ban" Johnny? Are you talking about you performing an action in response to Johnny's action? Because I'm talking about judging Johnny's action itself. It's like you see a mirage of water, Johnny sees a mirage of a city, admitting both of you are seeing mirages, and then wanting to ban (being upset at, or whatever equivalent works here) Johnny because he isn't trying to drink the "water".
