Fic breaks down many taboos, including that one. So... why not more in this fandom? Was the X-files just too early for that breed of radicalism?

Have you read Tikkun Olam yet? It's pretty radical.

This leads me to another (completely unrelated) point: has anyone else noticed that X-files fic written now differs greatly from that written during the original run of the show? I can’t put my finger on what it is exactly, but something important and elemental has shifted.

I think I know what you mean, but this deserves more than a throw-away comment. I will ponder more about this and be back.
