Personally, I find this whole argument irrelevant because I reject the premise that there is an obligation for the CD to tell his partner in the first instance.

Every day we all make judgement calls on how much to tell each and every person we meet. We do this in order to maintain relationships, to ensure our own safety and success, and in order to protect others from unnecessary harm and distress.

We make these decisions continuously. We all understand the goals to aim for, ie total honesty, but in reality total honesty is an impossible summit to reach. These are our decisions to make and we must live with the consequences.

It is not unethical to withhold information from another. However if we are to be considered a good, loving, trustworthy persons then we must reach decisions by carefully weighing the interests of all parties involved and coming to what we believe to be the best compromise. We must resist our selfish drives to tip the scales too much in our favor. We have an obligation to ourselves to ensure we do our utmost to be fair to everyone we love and value when deciding what we believe to be the best course of action.

So the ethics involved here is about how a decision was reached on whether to reveal the CD behavior. There is no obligation. Some SOs may get upset that they did not have the opportunity to decide for themselves but then there are others who say they wish they had never been told. There is no absolute right or wrong.

And if a SO is given the full facts, then she then goes through the same process of deciding if she should then inform others (with the partner's consent) or if it is best to withhold the information.

Included in that decision making matrix, should be the moral issue of educating the public and tackling transphobia. However understandably private relationships will be prioritized.
