It sure looks like they wanted him censored to me.
And it doesn't look like just an objection to the tone in which he said it, but rather an objection to the viewpoint itself.
Even if it was merely an objection to the tone, I think that would still be wrong or very questionable, because politicians need reasonable freedom to use the rhetoric of their choice.
Quote:
"We do not feel those comments were appropriate to be aired in a school environment in the manner he chose to do so, as they conflict with the inclusive environment of the school community and are at odds with the content of the school's curriculum.
"Whilst we fully support the principle that our students should experience a broad range of views and opinions, we cannot allow our schools to become a platform for views that are fundamentally incompatible with our approach and ethos."
