I do think the “playing” with gender identity for a large proportion of those who claim to have it is influenced by social media and potentially dangerous
Whilst I don’t disagree with your point, we are relatively powerless as most of the exposure is on social media and outside of school.
All we can do is educate with facts, so young people know as much as possible.
It’s important to know for example that being non-binary or gender fluid is not the same as someone that may consider themselves trans, and if this was something they wanted to explore when an adult, there is a significant process to go through, which you would hope means that only those that truly feel this way would explore this further.
