@sim While there's a >0% chance that this could be staged for social clout, there's a few things that suggest this could be genuine.
1. Children who don't believe in trans ideology are referred to Prevent, the country's counter-extremism programme.
2. Staff are known to push personal politics on to children. The parents are now expected to give up their kids so they can afford to live, while strangers raise them.
3. 'Mx' is a legally recognised salutation that may be used on government documentation, such as passports. It is a modern invention that covers gender non-binary (enby) individuals.
4. People who are attached to this get upset when others who not honour, or externally validate, their chosen identity. This teacher was likely reacting with emotion (i.e. irrationally) when they came across this student who either didn't understand or didn't agree with what the teacher was telling them to do.

The point of education is to ask questions. In today's society, you are expected to take protected topics at face value. This is but one reason why I don't wish to consign my children to public education.
