Trans people are mentally ill and clearly unfit to serve in the military. Suicide attempt rates in the trans community is around 40% verses 3% in the population as a whole. I'm sure medical professionals on this thread will back me up given the World Health Organisation lists transsexualism as a gender identity disorder in its current edition of International Statistical Classification of Diseases and Related Health Problems (ICD-10): http://apps.who.int/classifications/icd10/browse/2016/en#/F60-F69
These people need medical help rather than being encouraged to stay ill. That is all.
Steven you're back to talking utter shit again.
The ICD is purely a method by which peoples' overall condition is described, including social situation (where under sexuality). If you haven't noticed, just a little further down the page fetishism and voyeurism are described, but I don't feel that anyone here would classify people with those particular sexual interests as mentally ill.
You're not encouraging them to stay "ill" by allowing them to serve in the armed forces, nor can any "medical help" short of surgery impact them. If you recall we stopped the whole "gay conversion" thing a while ago when we realised it was torture and (like torture) achieved nothing.
There is no evidence that transgender individuals have any "weakness" in them any more than any other soldier. You're making baseless claims that they are "not much use in combat". I'm curious as to where you're getting that from, as it sounds like a personal anecdote, but I somehow doubt that.
Moving on, even if it were a mental health condition, you're essentially saying that nobody with a mental health problem may serve in the military, regardless of impact on performance.
What about everyone who's depressed? What about people with dysthymia? What about low mood? You're going to exclude 90% of all military applicants if you go down that road.
