There is no danger with transgender service members. In fact the military has already had trans service members for as long as it has existed, they just didn't serve openly and didn't transition while in the military. Your gender identity in no way effects your physical and mental ability to serve. As long as you can complete all requirements, they should be allowed to serve. The U.S. has a volunteer military force and people who chose to put their lives on the line for the country deserve respect and the right to fulfill their duty, as they have chosen. Further, many countries have openly trans service members with no issues and in the past yr in the US military there have been no issues. What specific dangers to trans members pose and what evidence do you have to back it up?
