AIBU to not expect my son to be exposed to so much shit at school?

[HadenoughnowFFS]

Son is year 1.
Sick and tired of him coming home with swear words the other kids have taught him, terrorism facts the parents have allowed them to watch on the TV, hitting each other as they're allowed to at home - the list goes on.
Teacher thought it nice to create a dog and diary.
Dog comes home with you and in the diary you find something from the newspaper to stick in and write a little about.
Comes home and the previous kid has an entry about the ivory tusks of elephants being taken off and more elephants being killed to death than being born.
Surely the parent can't have deemed this appropriate for a 5 year old to write about? And the teacher has just ticked it so clearly she does.
Aibu?

I do sympathise a little OP. I was upset when year 1 DS came home talking about "when the tower block went on fire and people were throwing their babies out of the window", because year 6 had chosen the Grenfell fire as the topic for their class assembly. I wondered if that level of detail was necessary, but I also realised that I'm lucky to have been able to have shielded him from the tragedy (until that assembly, anyway). Parents living on the other side of London, having to walk past the smouldering ruin every day with their children don't have that luxury.

Its good for 5 yo to learn about the killing of animals for their ivory.

I know this isn't about a child coming across the idea of death naturally. But I don't understand how a child of 5 does not know something about death, unless they are lied to and told things like that animal is really sleeping.

I didn't get the impression this was about death per se, as in elderly relatives dying or pets, but as in the intentional explanation to young children about sensitive issues they need not know about.

I disagree that the topic is unsuitable for all 5 year olds.

The typical 5 year old will know that meat comes from dead animals and that the animals we eat didn’t die of ill health.They will probably be aware of a vegan or vegetarian person and had that diet explained as not eating animals.
They may also have seen tv ads during children’s programmes like the one about snow leopards needing sponsorship due to hunters.
My local park has areas with signs requesting people not to let their dog loose and which creatures are protected etc. Typical 5 year olds are very interested in animal conservation and many will be watching animal documentaries which often mention the effect that man has on wildlife.

No YANBU. There is no reason to expose a 5 year old to the world wide news. Don't child psychologists advise against exposing them too much at this age, for their own protection? Google "child PTSD and the news" for plenty of such articles.

Same goes for the swearing. It's an unpleasant environment for children and can make them feel quite unsafe. It's inappropriate in a class of 5 year olds and should be challenged every time.
