If you're not drinking a specific wine every day so to speak, and are tasting the subsequent vintages of the wine every year, your pallet won't be able to tell the difference really.

That's how it is for most everyone, I think the disconnect is that the newbie isn't aware of that and make take the "expert's" opinion out of context or too serious. And the experts can be jerks too, but I think it's more people unfamiliar with wine seem to come into contact with the jerks first for some reason and wine gets a bad knock because of that.
