In his e-mail, Michael Kinahan wrote that he heckles young refs because it helps them develop as people.
In his resignation letter, Kinahan wrote, "... I am sorry some people failed to see the humor."
"It's not a joke," Chris Park, the registrar for the Scituate Youth Soccer League, told the Boston Herald. "He chewed out a 12-year-old so bad last year she said she won't referee anymore."
Kinahan wrote that, "I believe winning is fun and losing is for losers" and that he wanted "girls who will kick ass and take names on the field, off the field and throughout their lives."
