You know how some parents stop their children from playing games like Dungeons and Dragons and Magic: the Gathering because of their moral beliefs?
Well, when I was about nine or ten and just getting into Magic my mom created what was, looking back, probably a rule no other parent had ever set for their game-obsessed child: I was allowed to play Magic, but not allowed to use any black cards.
This did not upset me so much; I was already a tree-hugging do-gooder and wanted my decks to represent the forces of good, or at least not the forces of evil. But it only just hit me what an odd rule that was. The vast majority of parents would either think MTG is youth-corrupting “garbage” and demand that their children not play or just not care at all. But my mom had no problem with me playing, she just didn’t want me to play with the particularly evil black mana.
