While I wouldn't put it past a Catholic school board to ban GSA's at their schools. It makes sense - who's going to become a priest or a nun if people can live out of the closet and outside the clergy? But maybe they could stay away from the Nazi references while announcing the decision:
"We don't have Nazi groups either," rationalizes board chair Alice Anne LeMay. "Gay-Straight Alliances are banned because they are not within the teachings of the Catholic Church.
Xtra does a good job of framing this as an issue of school safety, as it is. And the school doesn't seem to have considered that angle before:
Pautler justifies the decision by saying the ministry's Equity and Inclusive Education policy only proposes GSAs as "one possibility" to fight homophobia.
Although he wouldn't provide another possibility, Pautler just stammers, "all students that attend school should be able to feel free of harassment and are protected from any forms of persecution or anything that makes them feel marginalized."
I'm assuming that at least some of the kids who get sent to a Catholic school would have internalized the Church's teachings on the topic, and that some of them might feel empowered to act violently on those teachings. The school will, of course, blame the bad apple instead of looking at the larger environment, ensuring that the problem persists.
If I didn't think these people were so uninformed about these issues, I might be tempted to say that's the intended outcome.
