No, sometimes we actually need to act before knowing everything. This is sometimes called “leadership”. What we know for a fact currently is that the number of children who think they are trans or non-binary is in a sharp rise in many countries in the west. There are guesses why this is: transactivists like to say that LBTQ+ is now accepted so these people dare to come out. The other side cite e.g. social contagion. Only in the west, somehow. If this is caused by something that is reversible, then that should be probably tried out.
