If it was in your post originally, then I’ll answer.
In my opinion LGBTQA+ is an umbrella term trying to cover too much to make sense, especially as Trans can mean falsely directing some potentially gay children towards thinking they may be trans., and falsely directing autistic chikdren, and children in care, or previously traumatised who feel they don’t fit in and see this as an answer.
As for Q for Queer? An odd person, someone living diffferently? So what.
Or does it suggest Queer theory: forget boundaries, because they are all false. This is poor safeguarding for children.
Love does comes in many forms, not all good just because it is ‘love’.
A for asexual as a relevant term for primary aged children? Are they supposed to think there is something wrong with themselves for not doing sexual things?
plus +?
If it were a family religions day being planned: Christian, Hindu, Muslim, Agnistic, Atheist etc probably people would complain mightily.
As people have already said, children are already told about different families, mutual respect, and not to bully people for being different.
As for bullying someone not toeing the line, the OP seems to be feeling quite stressed about not really wanting to attend because of what some people have said to her.
Someone on this thread a poster was was called bigoted for not agreeing with the school’s plan. This comes across as bullying.
It isn’t just LGBTQ+ agendas which are worthy of respect.
