It is sheer lunacy. There are physical truths to this world that are immutable. Water is wet, fire burns, gravity exists, Pitt sucks, etc... Human beings are a sexual dimorphic species. Sure there are some aberrancies such as intersex people, but exceptions do not disprove the rule. Intersex people or those with other chromosomal abnormalities do not negate that the vast majority of human beings fall into 2 easily identifiable groups that we call male and female. Just like those born with limb abnormalities do not negate human beings are a bipedal species with 2 arms and 2 legs.
Human beings are different from every other animal in that we have a highly developed prefrontal cortex. This allows human beings to transcend the primal urges and instincts that drive most other species' behaviors. Those primal urges and instincts are still there in humans and many people do let them run their lives primarily, but they are not devoid of the choice to be driven by these base desires like every other species. It is why human beings can self sacrifice when other species would not. It is also why some people can transcend the tendencies usually seen in most human males and females. Hence the concept of a "male" brain or "female" brain is ********. There is only the human brain. Masculine and Feminine traits are not arbitrary concepts, but rather observations across generations where certain traits were seen more in human males and others more in human females. Hormonal development certainly tends to influence humanity, but the prefrontal cortex can conquer all. Thus a female who exhibits more traits commonly seen in males is not a male or having a male brain nor is the reverse true. Behaviors do not determine male or female. The male/female binary is an observable and objective finding based upon chromosomes. This leads to which hormone predominates during both development and adulthood which in turn directly affects physiology such as genitalia appearance, bone density, bone structure, muscle/tendon density, etc...
People who feel uncomfortable with their biologic male or female status have gender dysphoria. Its a simple, straight forward description of the condition in that the person is not happy with the physical realities of their body. Males who believe they ARE, or can BECOME females, and vice versa are delusional. These people believe to be true something that is not consistent with physical, objectively observable reality. There is more reason to believe the schizophrenic who claims the government is sending them secret messages through the radio than that a biological male or female claiming to be anything other. Yet the schizophrenic will be labeled delusional without a second thought and the current thinking is that reinforcing delusions is detrimental. While the delusion that is transgenderism of being something objectively inconsistent with reality ARE reinforced. Take the example of a person suffering from body dysmorphia in the form of anorexia. This is a person that is delusional in the fixed belief that their objectively observable malnourished body is in fact obese. Now imagine giving that anorexic the fun house mirror that makes everyone look wider, encouraging them that they really are fat and should keep living out "their truth" while demanding everyone else do the same in encouraging them to lose more weight. It is not only incorrect, its is ******* INSANE AND HARMFUL. Yet this the exact same as validating a transgender person.
EVERYTHING else in the mental health world is about trying to help people cope with realities of the world they are unhappy with a healthy way. A depressed person who feels as though the entire world is conspiring against them does not need that notion reinforced. An emotionally crippled introvert does not need to be told their feeling that everyone is watching and judging them is well founded. The narcissist does not need to be told that they are in fact the center of universe. And the transgender person does not need to be told that their unhappiness with the realities of the world are best managed by simply ignoring those realities and substituting their feelings instead.
