Are people really going around screaming "Nostalgia!" without any supporting statements behind it?

Generally, if I ever use the term then it will include all the things that were previously overlooked from the original post (thus why nostalgia is at play).

The way I see it:
My Con's match your Pro's = "Stop Liking what I don't like"
My Con's were not included with your Pro's = "Nostalgia"
