Benjamin Disraeli

I grew up when people were afraid to 'come out' as gay. If you asked me how many gay kids I grew up with or went to school with, I would have said none - which of course could not have been true. The truth is I have no idea how many confused and frightened kids I grew up with. They are still out there.

You can also make explicit certain social problems which, again, would be prejudged or not encountered at all in real life, because people have set up defenses against it. Fantasy allows you to get past defenses.
