Most people in the US think this form of medicine is unreliable enough to be worthy of a straight-up ban. In the UK, where they had an actual scientific review about it (which I note upthread the progressive side of politics is still talking smack about 
) the number favouring a ban for children is between 75% and 87%.
So yes, this is the centrist position. “Gender medicine works” and “a person can be actually a woman despite having a male body” are minority positions.
If you were talking to a centrist on this issue, would you be able to have the intellectual humility to admit that you are the one with the minority opinion, and it is possible that they are the ones who are right, not you?
