Good point, but I think saying "milk is milk" doesn't depend on the definition of milk - it could have any definition, but "milk is milk" would still be true. More generally, "an object/concept implies itself" is true regardless of the definition. Other examples might include (lifted from wikipedia) "if p then q; p, therefore q" and "there are no married bachelors", although the latter could fall into the trap of culture and history you mention. This is meaningless in any useful sense except for our purpose, right? That there are basic facts that we can point to and say "this is a fact".
That way we can remove cultural and historical biases from these "candidate facts". If we have arrived at a candidate fact then we can decide if that fact can also be an opinion.
i.e. it's easy to look at an opinion and say "is this a fact?" but let's try to do the opposite: look at a fact and say "can this be an opinion?"
edit: I'm no philosophy major, and from reading wikipedia I may be conflating "fact" with "logical truth"
How fortuitous! I'm currently taking a class on Discrete Math and this is a perfect opportunity to break out the P's and Q's!
Maybe we could try doing a proof by contradiction to prove that a fact can not also be an opinion, but I fear that this whole conversation is dangerously close to being a proxy for a semantics debate. I'm not sure how to start trying to do a proof for this in the first place, but I'll try it out when I finish with my econ homework.
As for a fact that *COULD* also be an opinion, what about facts that are proven to be false? For example, "There are 9 planets in the solar system." That fact used to be true, but now it is false. Is it still a fact or has it turned into an opinion? If it is no longer a fact and has become an opinion, it would imply that whether or not a statement is a fact or opinion depends on time- which from certain perspectives could be used to argue that the statement is always both fact and opinion, and only becomes either a fact or opinion when people talk about it.

Oh dang, a word I've never heard before!
Thanks, Scytale! I'm always looking to expand my vocabulary.
Nice! New words are the best. 'Conflating' is a good word- but an even better new word.
