No, I think things like this that can cause a potential dangerous situation shouldn't be told. Coming out about anything, sexually, gender identity etc is a personal choice. Taking that from someone is a form of control.
If a teacher tries any of this shit when my kiddo is in school, I'm gonna lose it with them. It's up to my child if and when they feel comfortable telling me those things, if they ever realise they aren't straight or aren't the gender they were born as. It's their right to choose to tell me this. Not someone else. Just because they're children, doesn't mean we have rights to know everything. Their privacy is important too. Children are people, not possessions. They deserve respect. We don't demand someone's boss tells their family if they find out this stuff. We don't demand higher education teachers of over 18s to do this either. Just because their minors does not mean were entitled to know their private thoughts and feelings. Unless a child has admitted to thoughts of suicide/ harming themselves or others, I don't believe we should be told.
If they think a child has behavioural issues that need looking into, fine. That's good information. But outing someone, no matter their age is wrong and potentially dangerous. Luckily there's parents out there who will be accepting if they get information like this. But unfortunately there's parents who won't be, and depending on what those parents are like, it could result in some seriously bad situations arising.
I know my own parent was less then impressed when she found out Im pansexual. And they tried the whole 'but kids' and 'its just a phase thing.' which isn't as bad as some people/ children would get. But being invalidated doesn't feel good, especially on something that isn't an opinion, but a fact. Being told you're wrong for your sexuality or gender identity can do a lot of damage to people.
This is stupid. It shouldn't be a thing. I'm sick of the 'but the children' bullshit the government keep pushing as a cover for wanting more control. No end to end encryption, because we want to protect the children. Our children, because we want to protect the children. Access to your private messages, the children.
It's all bullshit they use to get people on board because children are an easy pawn to use. The government's of the world need to stop using children in pawns of their stupid games and just be honest. But how likely are people to listen if they say 'we want more control' over 'we are trying to protect the children!'
