I've seen some faux outrage and absurd virtue signalling over this new ban on transgender in the military in the comments under this blog post LGBQT community takes a second hit and this earlier one John McCain Backs Transgender Ideology Slams Policy 

"Discrimination!!!"

One person claims he served in the military, but I guess it was so long ago he's forgotten that the United States Military is not a place for social experiments.  It has one purpose and one purpose only:  to defend the nation from our enemies through superiority, readiness and lethality.

It's not discrimination to deny transgenders to join the military, no more than it is to deny those with flat feet or being too short - or too tall -  or not having good enough vision.   As an American, you have certain rights guaranteed you by the Constitution, but there is no inherent right to serve in the military.  We deny the right to serve to not only those with physical disabilities, but also to those with criminal records,  drug users or even those with various medical conditions.  (the Marines have been known to deny otherwise perfectly healthy individuals who happened to have an arm tattoo)

It's also not discrimination to deny someone with a mental illness to serve in the military, and it's accepted by medical professionals that gender dysphoria is a mental disorder.  Those suffering from this ailment are nearly ten times as likely to commit suicide as the overall population. 

Those who have transitioned need to maintain constant medical treatment because their body is constantly rejecting the operation.  Others require a constant need for hormone therapy and this affects their readiness and hampers their ability to be deployed on a moment's notice.

One needs only to look back at history to learn how the dissolution of gender leads to the eventual fall of a culture.  Camille Paglia, (a noted scholar who also happens to be a lesbian) points out "Historically, the movement towards androgyny occurs in late phases of culture as a civilization is starting to unravel.  You can find it again and again and again throughout history, in the Greek art, whether it's the Hellenistic era or the Roman Empire.  What you invariably get in response to this decline in culture are people who are convinced of the power of heroic masculinity on the edges of the weaker culture, whether they're the Vandals or the Huns or whether they're the barbarians of ISIS."

If we are to remain a powerful and sovereign nation and keep the barbarians from our gates, the military must maintain a strong, lethal and alert fighting force.  Any compromise or placation would be detrimental to the entire country.   It's not discriminating to think that way;  it's survival, both as a nation and as a people.  I'm not sure why certain persons are arguing this unless their intent is to weaken this country.  If that's the case, then they're more dangerous to the survival of this country than are our enemies. 

“A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murderer is less to fear.”
