You: "something that has been researched for a bit literally refutes your thesis statement that there is no long term data right out of the gate!!!"
Also you: "It doesn't help that the Nazis burned a lot of that data"
So, the second half agrees with what you said, "we have no long term data", and since that is true, and we are having to start over, the first part of the OP is also true.
Moreover, show us where the treatments being used today were anywhere in use at any time in the past. So much of what is being done now is based on new drugs, and/or more advances surgery techniques. Except drugs that have been used for some time to chemically castrate sexual predators, but it is definitely new to be using such a drug on children.
Where most of this is new is in its application on children. If the Nazis were researching this, we can align such treatments with torture and crimes against humanity. I think most reasonable adult human beings would classify much of this evil in that bucket.
Of course, liberals are not reasonable adult human beings. Given their penchant for rabidly wanting to murder their unborn children, I think it a stretch to call them human beings at all. Monsters would seem a better fit, don't you think?
