It may just be an impossibility for many of those who are cis-gender to ever truly understand the premise that a woman born biologically a boy was always a woman. The fact is, that there is a non-tangibility for the majority of the cis-gender population to understand what this means truly....because they have no reference point. Honestly, I think we need to be careful who we vilify because what one sees that may be considered as vilification may, in fact, just simply be true lack of understanding. Now, considering that it took me as an intelligent (so I am told) human being four decades to understand that my childhood experiences actually paralleled that of most biologically born girls rather than as most biologically born boys and that my identity was always as female is likely a harbinger as to what we might expect from a cis-gender person who has ZERO concept likely of what the true difference is between gender and biological sex. Personally, I am not entirely sure that we will ever be successful in being able to frame a point of reference that is even close to understandable because of this. True enough that the media ticker tape of "use to be a boy" flashing on the bottom of the screen does trivialize the intent of the mission she is trying to accomplish as a person and adds unnecessary sensationalism. The likely culprit there however is more likely the network "packaging:" this and in this case, the network and the show's producers would be lax here for taking a myopic viewpoint rather than focusing on the crux of the points she was TRYING to convey.
