Who say it is wrong?

I think it depends on context? If someone wanna refer to a group of trans people to discuss about their struggles, experiences, etc... by all means they can use the word. Otherwise I don't see a reason to treat trans people differently from cisgender people.

I have a trans male friend and I just treat him as a regular guy.

I remember using the word "bromance" when my parents asked me why I was too close with a guy from school. But sure...
I'm all for trans rights. I don't claim to know a lot about "male/female medicine and condition" but people working in the medical sector should remember their Hippocratic Oath by treating everyone the same regardless of their gender identities and try to be as professional as they can.

I think you're nitpicking very rare situations to justify adding a single line in birth certificates.

If doctors are lousy enough not to do thorough examination, then that's just negligence on their part.

The government should put in place a policy that bans gender-discrimination in healthcare. Doctors should be educated to probe on their patient's gender identities regardless of what it says in the form. Patients should feel comfortable sharing their history of gender transition (if any). Etc...

I agree it is an issue in medicine. But I disagree it should be resolved by following the status quo. 

What sort of accident? Is the gender of the patient relevant in treating the patient?

In the US, 1 in 4 transgender people were denied equal treatment in health care settings. Cannot find a similar study in Malaysia, though. 

Patients have the reponsibility to tell the truth, yes, but we live in a society that views trans people differently besides all kinds of stigma. Why should doctors assume their patients are being truthful all the time? A doctor must perform due diligence and ask follow up questions.

As a gay man, I'm not supposed to donate my blood but I donate my blood every 3 months anyway. I lie at the donation form all the time because in the blood donation process each sample is sent to the lab for HIV testing before the batch is accepted anyway. So far no one come knocking at my door to arrest me yet.

that is true if the doctor is blind and mute, thus couldnt see to identify, and couldnt ask to determine

yes if the doctor never determine on the problem and proceed to apply a remedy

having our blood type on our mykad is easy..but never done. and yet we dont see hospitals start transfusing blood without determiining what's the blood type.

if a hospital or doctor do that, transfuse blood without determine blood type, got it wrong and killed the patient..is it the doctor's fault then? or the blame can be put into 'why blood type not being listed in mykad? why a mechanism was not applied to avoid this?'.

Just to be clear you just want both gender and sex in our identity cards right?

Just to be clear you just want both gender and sex in our identity cards right?

Someone can enjoy cross-dressing and still identify as a man.

There's a middle ground here. Just put sex and gender in our identity cards. I'd be behind that. Add details on our blood type too for good measure.

I know some of our local trans activists are fighting to remove religion from their identity cards because they are sick of being subjected to the discriminatory syariah laws. So the aforementioned demands would just be an extension of that.

if a doctor need to prescribe a solution that makes a difference whether the patient is a male/female, i am under the impression that a check is needed..like for example, actually holding out the said patient's penis if assuming that is the problem that needs to be dealt with.

unless you're giving me a scenario where the patient was born male..but is a trans that already have his penis removed....and if yes, i dont see how that penis could still be a problem that needs to be dealt with

but you might have better scenario/example..so shoot..so we can discuss

Oh okay. I thought you're citing your friend as the representative of trans community or somethign.
