Riittakerttu Kaltiala should certainly be on the panel, and someone from, say, Sweden.
And at least one of the critical researchers into puberty blocking and the Dutch protocol. Stephen Levine or Julia Mason or, more generally in the wider field, Michael Biggs.
And as I noted earlier, given that this panel is going to recommend 'inclusive care' rules, it's important that the panel understands how forcing gender identity ideology on everybody, including people who don't share the religion, means that many women, in particular, will feel excluded and humiliated and ridiculed by having their sex-based gender labels turned into body parts or functions. (Men would feel humiliated, too, if they were actually dehumanised in the same way as women already routinely are.)
In other words, the panel should not simply ignore the clash of rights or the clash of the needs of various demographic groups in the recommendations it makes. Everybody should matter here.
