For humans sex is binary and immutable, and it does matter. The vast majority of people understand this simple fact. Nevertheless, nowadays this have become unspeakable and, instead, there is an incresing trend of talking about sex being a spectrum or a social construct, playing the pronouns game and using "inclusive" language.

That being said, I'm not convinced that most, if any, transgender ideology supporters actually believe any of the things they said. I think they too undertand the reality of sex; however, they won't admit this aloud. Whatever their real reasons for doing so are, one commom justification is this: it's polite and it cost nothing. Obviously, it's false that it cost nothing, but trying to argue this point is useless because TiMs rank higher than women in the Oppresion Olympics... So, intead, I'll challenge the idea that is kind to play along with trans' fantasies.

Is it kind, for instance, to tell a schizophrenic person that the voices he hears are real? Even if these voices are telling him to do something dangerous? Would it be appropriate to tell to an anorexic teen that, yes, she is fat and she would benefict from a liposuction even thought she is actually underweight? Should current treatment for anorexia nervosa be declared a form of conversion therapy? I suspect a lot of these people would answer no to these questions, but they may say these examples are not comparable with trans. "What is the damage in playing along with trans, especially when not doing so cause them so much distress?", they may ask.

The damage is they are setting them up for failure. Changing the meanings of words don't change reality. Regardless of how hard they try to emulate the opposite sex stereotipes or how much hormones they take or how many surgeries they undergone, men can not become women or vice versa. Sooner or later, many trans will face this reality. They will realize that, even though they may have undergone irreversible body changes, they have been pursuing an impossible dream and transgenderism was not the panacea they were promised.

Furthermore, lots of supporters are chanting TWAW and TMAM nonstop, but how many are willing to walk the talk and date an tran indivual of the sex they are not atracted to? And how many are willing to date a post-op trans individual of the sex they are atracted to?

Another example is the health care for the rare case of trans who "pass". Sex is quite important in this context: the prevalence, symptomatology, diagnosis, prognosis and treatment of a disease may differ between the sexes. However, if such a person is registered as the opposite sex, they may be putting their health or life at risk.

There may be more examples that show that playing along is not as kind as they claim, but these were the first that came to my mind. And I suppose it's not worth saying any of this to the "true believer" (they will never listen), but can it persuade a more casual supporter?
