Didn't I just say:
So, taking into account what I said above, what makes you think I'm "looking down" on anyone, putting anyone down, or considering anyone as lesser?
If mental illnesses, defects, or disorders aren't recognized as such, but treated as "normal", it puts those people in a dangerous situation, such as the high suicide rate. One wonders whether or not those lives could be saved.
What's more important, a parade, or preventing a suicide?
Then investigate it, find out if it is.
Officially it's not, but there are mental disorders associated with being trans that some trans people suffer but others do not, the state of being trans is more associated with a phenomenon referred to as "Gender Euphoria" which is a sort of satisfaction or comfort associated with performing an action assosciated with whatever you picture yourself as, that could be anything from wearing a dress or a binder or whatever, however medically a lot of clinics require that you suffer from a disorder referred to as "gender dysphoria" which is a discomfort or anxiety associated with performing the gender you were born as, commonly for people assigned female at birth this has to do with discomfort with their chest or voice and for people assigned male at birth with having large amounts of body hair, broad shoulders and such.
There are other mental disorders that are common in transgender people such as "impostor syndrome", "Depersonalisation Disorder" and "Derealization disorder" as well as Manic Depressive disorder, of course there are other things those are just the ones I can remember off the top of my head, but these are all things I found out by researching in the Internet and asking people, in any case I will not participate further in this discussion as during this month I've had to talk two different trans people out of suicide and as such I don't believe I can continue this discussion in a calm manner.
So anyways, if you want your answer you can consult medical journals but officially being transgender isn't a disorder and if you want to prevent suicide it's very easy, just don't question people on what they are, stop treating them like freaks, stop using slurs, show them empathy and such, as for mental care there are psychologists specialising in this field and the first step generally recommended to transgender people is to talk with them, but like I've mentioned before, this isn't really your business to be questioning around on the Internet, if you really cared you would have researched this already I have it's not hard at all, though granted I'll admit my intentions are more that I'm may be suffering from one or more of the disorders that were previously mentioned (I don't know yet it takes time to diagnose) and as such I wanted to know everything that could imply, but still all the information is available on the net if you really care, there's no need for anyone here to answer your questions.
