So it turns out that the rabble of religious loons were basing a lot of their protest on fake news and only a few of them even had any connection to the school in the first place... the rest were just angry religious idiots:
Yeah, it's normally the case when these sorts of people turn up - they just want to kick off and will fabricate all sorts of nonsense, in order to make a song and dance.
As far as I can tell, the curriculum itself is mostly centered around the fact that LBGT people exist, and simply allows children to understand that it's a fact of life. The objective is that will give children a better understanding of the world they're growing up in, presumably this will also help tackle things like bullying.
When you actually look at the guidelines what's being taught is pretty benign, sensible and straightforward in nature.
However - when you listen to the rantings of these religious loons at the school gates, some of them are talking as though primary schools are teaching kids to go to parks late at night and have gay sex orgies, or whatever - but it's all just fake news.
And again, it's always interesting how the types that turn up with these sorts of views, are often from out of town and have nothing whatsoever to do with the local community.
