In your opinion, is someone going through a transition considered them putting themselves through a mental illness by choice?
If you would say these people already have a mental illness, and are just choosing the wrong solution for it, what do you mean by "mental illness should not be condoned?" How would someone go about solving their problem?
Whatever mental or physical effects they are experiencing that they feel they need to alleviate. I also allowed for the idea that they falsely believe they have a mental illness.
Simply though, can you clarify your position on what is really happening and what people should be doing (or not doing)?
