What would Jesus wear on his T-shirt?

With hundreds of students at the Homewood-Flossmoor high school planning to wear T-shirts that say "gay? fine by me" on a "gay awareness" day, some Christian students have decided to argue with the message with T-shirts of their own:

[T]he T-shirt campaign, which made a quiet debut last year, is meeting opposition from some of the school's Christian students. In what will amount to a schoolyard battle of messages, a couple hundred other students are expected to wear shirts citing "crimes against God," namely "discrimination against ... my 10 Commandments, my prayers, my values, my faith, my God."...

Jacques Jacobs, a youth minister at Family Harvest Church, said his church is "not fighting anybody, we are only standing up for the rights of the Christian student."...

David Thieman, a Homewood-Flossmoor school spokesman, said both contingents could wear the shirts as long as they comply with the student code of conduct, which forbids the promotion of violence or drugs.

UPDATE: And to answer my own question -- what message would Jesus wear on a T-shirt -- I'm going to go with: "Love one another." Do you have a better idea?
