Transgendered person who served as a highly decorated Navy Seal for 20 years. Explain to me how this person who functioned at the highest level possible in the armed service destroyed cohesion and effectiveness. The vast majority of people aren't even capable of qualifying for the team this person was a part of for decades.

If someone is capable of serving and you have to believe the testing is rigorous enough to wash out those who aren't capable, who cares about gender.?
