One of the pages on that instagram post states'
'Binding, for those who don't know, is very common within the trans community, specifically for trans men or non binacry people, as it can help reduce gender dysmorphia. However, if done incorrectly or unsafely, binding has the potential to be harmful.'
'Promoting awareness surroudning binding is vital - schools have a responsibility to keep trans youth safe.'
This post is really missing the point isn't it. That newsletter does NOT talk about the negative effects, it just links to sites that also minimise the negative effects.
I think from seeing that instagram post in its entirety, we can assume that there is a bit of a gap in safeguarding here. Or that the headteacher has not really proof read the newsletter.
In the meantime, there is nothing but fingers in the ears shouting 'you are all phobic' in response. Maybe the headteacher will see some sense in the very glaring issues of those links today. Maybe not.
