I asked a question about a scene in a movie that not only takes place during ww2 in Vichy France but also ww2 and the persecution of Jews are absolutely central to the film which is Au Revoir Les Enfants.
I believe that the ww2 tag, which is surprisingly to me new, belongs not just on my question but would serve to help attract answers and simply interested readers. I often search by tag and if ww2 was associated with The Man in the Grey Flannel Suit (a movie which takes place a decade after ww2's end but is still very important to the movie which is ostensibly about a writer in the advertising or public relations business in NY in 1955) would allow people interested in ww2 as a general area to potentially discover a film that might interest them and it might also attract knowledgeable potential answerers. I have been very successful using tags in scifi, creating new ones occasionally, but now I am told I do not understand how to use them. By successful I mean I have gotten I think faster and better answers as well as attracting sometimes well over 1000 views.
Finally, what harm does creating a new tag do and what harm does even mis-applying one do? Not that I agree that I have misapplied the ww2 or the Malle tag (I was hesitant about the Malle tag since I thought very few people would search on that tag or even know, at least among Americans, who he is.(
