I am very much against the nostalgia goggles argument and I think people who use it need to reassess how they communicate. I have never seen this argument used effectively or with a modicum of intelligence. It may be justified in some instances, but I'm not aware of any. How can you possibly know why someone prefers something? It's presumptuous, unfair, and generally baseless.
Hardly presumptuous if the person proposing the argument actually took the time to analyze the opposing argument. If the opposing argument contains hints of nostalgia-laden bias then it is entirely possible to know why someone prefers something due to their nostalgia. Anyone who's ever been in a debate should know better than to just assume (it makes an a** out of you and me). That being said, one can easily assess hints of nostalgia bias by analyzing the argument in question. Furthermore, I like to think that it's unfair to all parties involved if the opposing party is so caught up on the past (nostalgia) for incorrigible reasons that he fails to address the other side (the present or future). Also, if anything, it tends to be the person wearing the nostalgia googles who's using a baseless argument.
Just a few days ago, a Pokémon fan mentioned having a distaste for the current generation's designs. That in itself is okay; not everyone is going to fall in love with every design that Game Freak hurdles at us. However, the fan in question went on to use the argument that the first gen Pokémon had better designs overall, because its Pokémon were more animal-like, and the current gen sucks because there's a Pokémon based on a sword and a tree—as if the first gen didn't have its fair share of Rummage Sale Rejects. (magnets, piles of goo, humans, disembodied whack-a-mole heads, etc.) Said fan even went so far as to say that Game Freak has run out of ideas, based on the aforementioned "sword" and ""tree" Pokémon.
What's worse is only a small portion of the current gen's Pokémon has even been announced. How is it possible that two off-putting designs makes the entire gen suck—before the entire gen has yet to be revealed? This is the part where the person wearing the goggles forgot to even take into consideration. He failed to consider that upon the unveiling of more Pokémon, the ratio of favorable designs might increase, and there may not be as many bad designs as he initially thought; he failed to acknowledge the fact that there have been bad designs in the past that should receive the same judgment as the "sword" and "tree" Pokemon under the logic he used (not to mention there have been a number of flower-based Pokémon in every gen to date [so why not a tree?]. Most of all, he forgot to entertain the concept that perhaps it is not the Pokémon games that have gotten old and played out but perhaps it is he who has simply "grown up" and the series just doesn't interest him anymore.
The Nostalgia Goggles argument is suitable here.
HOWEVER, the greatest, most irrefutable, real-world example of Nostalgia Goggles can be seen in older generations who claim that crime rate has skyrocketed, youth has gotten dumber, and every possible thing "back in their day" was better (etc.)... ignoring any possible negative event that ever happened back then as if they NEVER EXISTED.
