In the fourth grade, I had the toughest teacher of my life: Ms. Daly. She wasn't physically imposing, or necessarily mean; she was smart, tough and didn't take any crap. She was going to teach us, and we were going to learn, come hell or high water. It's like she combined the roles of parent and teacher into one authority-figure superhero. That year, I had my first proper fist fight.
Many of us (Christians) think we should voice our objections if we hear or see something we perceive to be immoral according to how we interpret the Bible. And we often do this without being asked, without having a relationship that gives our opinion context, without knowing where the other person is coming from.
