The story reflects a family’s journey from a place of ignorance to one of acceptance and celebration
Not so long ago, people who were transsexual suffered from a medical condition of gender dysphoria. This made them feel that they had the 'wrong' body, and the only solution for some of these people was to take medication for life in the form of cross sex hormones, and have major surgery. Most of us would be sympathetic that anyone had to go through such things.
How did we get from there, to somewhere in which being transgender is something to celebrate? Whilst simultaneously having to see such people as the most oppressed on the planet.
To put it another way, how can those of us who are not transgender be considered as the most privileged, whilst also viewing trans people as having a condition which should be 'celebrated'? If we're supposed to celebrate their condition, doesn't that make them the most privileged - the lucky ones? And if they're less privileged, isn't 'celebrating' their gender dysphoria a bit like celebrating because someone has epilepsy, or diabetes, or anorexia?
