Let me see if I understand you correctly:
Let me put it another way. Movies about sports competitions or other contests, in which the plucky underdog hero wins against stiff competition in the end. Do you also object to these, on the grounds that they will only discourage real-life competitors who (as usually happens in real life) do not pull off against-the-odds wins?
A note to my friends: Since understanding what was happening to me, I manage my issues (I consider myself a "recovering depressive") and do achieve genuine holiday cheer these days, so there is no need to walk on eggshells in my presence. I do genuinely hope that everyone who celebrates had or will have a Happy Hanukkah, Merry Christmas, Joyous Solstice, or Good Kwanzaa. If you don't feel like celebrating, I hope that you can find a "warm, dry, comfortable hole" to crawl into and wait it out.
