Again, it's cultural, but that doesn't make it subjective. The fact that it will be different in the future doesn't tell you that it's already different now. There is a fact of the matter here on which everyone already agrees; it's as objective as any other fact.

Yes, it does. Unless you subscribe to popular=objective, which I do. It is different now though. Looking at the past tells us that. It isn't like every other fact. There is a lot of disagreement in this thread. It isn't a fact like 2+2=4 is a fact.
