The talk of banning trans people from the military started with a tweet (obviously) from Trump in July of 2017 in which he discussed how trans people are a disruption and a financial burden due to medical care.
As far as the financial aspect of trans people in the military, they make up such a small population of the military that costs would not go up significantly. Anyone who knows someone that is seeking gender-affirming healthcare knows that it is expensive, but the military seems to think it is too expensive to pay for.
The RAND Corporation covered the statistics of trans healthcare, too. Gender-affirming healthcare would only increase costs by "$2.4 million and $8.4 million annually, representing a 0.04 to 0.13 percent increase in active-component health care expenditures." Those might seem like big numbers in a raw dollar amount, but in the grand scheme of things, you can see that the percent of things do not increase more than even a 0.50 percent increase.
The trans military ban is wrong in so many ways. It's fueled off of hate and bigotry. Not only do its fundamentals fail to stand on their own merit, but it affects people's lives and their well-being. Though the number of trans people in the military may not be large, they are still there and they will suffer because of this. Some people may become unemployed, their mental health may go downhill, they may lose access to all their healthcare — not just gender-affirming healthcare — and it will severely damage their future and ours as a society.
This doesn't just impact us now, it changes our future and it will harm so many people's lives.
