Our sons attended a Christian Bros. high school. A few years back a religion teacher had a gay friend speak to her class about relationships, and allowed him to bring in his "wedding" pictures. No notice was given the parents and needless to say there were a number of outraged folks who mounted a campaign for her dismissal. There was an equal number of parents who supported her retention. The controversy resulted in a fullscale review of the religion dept. by the Christian Bros. themselves, the installation of an overseer to conduct ongoing audits of the dept, and the resignation of the principal.
What got the ball rolling was the initial contact with the Archbishop at the time - a new feller to the area, name of George. His response was overwhelmingly encouraging and supportive of those of us calling for her ouster and no doubt fostered the Brothers expeditious involvement. Unfortunately we lost him to Chicago, where he's now a Cardinal. Great guy...
Forgot to mention that the teacher was suspended for a year and assigned to "refresher" courses on Christian Bros. education, before re-instatement. She chose not to return.
