As Michael Hoos stood ready to march on the freezing, winter morning of Jan. 22, he held a sign, made by one of the students at St. Agnes School, Catonsville, which read, “Give me a chance to rock your world.” He said it reminded him of his adopted son, who is learning to play the guitar. “I tell him to praise God everyday that you weren’t aborted,” said Mr. Hoos, admissions director for The Cardinal Gibbons School, Baltimore.
