If you have seen the headlines claiming that President Biden reversed President Trump's "transgender Military ban", then you have been duped by FakeNews and leftist propaganda. This lie has already permeated the left's alternate reality where we'll be arguing it for years, and the facts will only irritate them.
- From the 1960s until about 2012: People with “current or history of psychosexual conditions, including but not limited to transsexualism, exhibitionism, transvestism, voyeurism, and other paraphilias” were barred from enlisting in the military.
- In 2008 Obama stuffed the pork-laden Duncan Hunter National Defense Authorization Act  with a diversity and inclusion "Studies", and in 2012 President Obama’s secretary of defense (Ash Carter), under the cover of their FakeScience recommendations, announced that while while other paraphilias would be banned from military service those transgenders currently serving would be allowed to continue serving. New enlistment remained prohibited.
- One year into the Trump administration (2018), a policy was enacted briefly allowing transgender enlistments (adding not removing liberties), but Secretary of Defense Mattis quickly qualified that policy with a restriction that “transgender persons with a history or diagnosis of gender dysphoria — individuals who the policies state may require substantial medical treatment, including medications and surgery — are disqualified from military service except under certain limited circumstances." They continued to allow people who are already serving openly to remain, as well as any who would serve “in accordance with their birth gender.”
- The media misreported it as a ban. That's not a ban. That was an INCREASE in diversity, and even trans diversity, but putting a cap on how serious a disorder could still effectively serve, as that wouldn't do anything to help military effectiveness, and would stick taxpayers with large bills (≈$132,000 per surgery). Without this, anyone that wanted could enlist, get the surgery at taxpayers expense, then drop out once recovered.
- In 2019, a panel of the U.S. Court of Appeals for the D.C. Circuit ruled that the policy is not a “ban” because “not all transgender persons seek to transition to their preferred gender or have gender dysphoria.”
What really happened is, “Biden orders military to pay for gender reassignment surgeries, and take on the severely mentally ill". Remember the facts that post-op transexuals have extremely high suicide rates, depression and other emotional issues, require extensive therapy, and many regret the surgery and would take it back if they could. I think these people deserve compassion, but we probably shouldn't be recruiting them to give them weapons (to the point some might have their fingers on the triggers of our Nuclear arsenal), all in the name of wokeness. You can be excluded from the military for a variety of physical or mental variations (weight, height, substance abuse, education, bad finances, earrings (ear gauges), tattoos, criminal record, and so on)... but if you want to stick Uncle Sam with your gender reassignment surgery and make the military liable for any hysterical outbursts that hurt others, Biden is all for it.
