The real issue here is: What is truth?
1. That the trans person is suffering from a personal problem created by a condition that causes them to see themselves as a gender different from their sex.
It's obviously true that if someone thinks they are a gender other than the biological gender they were born as; they are suffering from a "personal problem".
Therefore, the best option is to just play along and let them present themselves however they want. This will ultimately reduce suicide in the trans community.
This statement is false; because "playing along" ultimately does not reduce the suicide rate in that community. The LGBTQ+++ community still has the highest rates of suicide and mental health needs per capita of any other population and this is true even in nations that are very liberal in accepting the "life style".
The only exception to that, (in regards to suicides per capita)
might be combat vets? We know 22 veterans a day commit suicide; but that percentile "per capita" is among how many veterans total?
But LGBTQ+++ only account for maybe 3 to 4% of any given ("liberal") nations' population. And this is including homosexuals in that stat who identify as their birth gender; not just trans people. Trans people are a smaller subset of the larger LGBTQ+++ population. And I'm guessing the new statistic is that trans people have an even higher suicided rate than homosexuals.
Adding to this; that the "trend" seen, is an explosion in the trans stat over the past 10 or so years, that only includes people under 21 years old. And here's where the issue is. If an adult wants to cosmetically alter their appearance; that decision is on them. (And they aught to foot the cost of the surgery themselves too!)
But if you're dealing with a bunch of 5 year olds; consistently telling them they might not actually be the gender they were born; one has to keep in mind, that's a population that also believes they might be unicorns, Spiderman, or Pocahontas. So, consistently reinforcing gender confusion in children starting at that age; is a reflection of the psychological instability of the people pushing an agenda!
And
THAT should not be happening!
2. The trans person has no problem. The problem is with society not realizing that there is no significant difference between man and woman, even biologically, and gender and gender roles are all just made up relics of the past.
This statement is also fundamentally false.
There is a kernel of truth that certain aspects of "gender roles" are determined by what's acceptable in society. Generally women take care of small children. That has historically been the case, seeing how prior to maybe the mid 19th century; basically the only food source for infants was human breast milk, which is only produced as a result of pregnancy. Not that men can't take care of children. Many men successfully do so and are very good primary care givers. (Also prior to the advent of effective baby formula, as well as advancements in medicine and hygiene; the infant mortality rate was much higher than it is today.)
The vast majority of people in industrial societies no longer believe that women can't be doctors, lawyers, engineers, construction workers or serve in the armed forces or law enforcement. Nor do they believe men can't be school teachers, nurses, or occupy secretarial type jobs (men have been school teachers and nurses for centuries).
Yet "gender roles" still are determined by the occupational choices individuals make, that are fundamentally driven by the make up of the psychological and physical differences between men and women. Engineering, construction work, police and militaries are still "male dominated" and child care, nursing and (at least school teachers for younger children) are still "female dominated".
So no, it is a lie also that there is no significant differences (be it in terms of biology or psychology) between men and women.
