Dont ask dont tell policy should gays be allowed in the military argumentative

This is a research paper but also an argumentative essay of my choice. should gays be allowed to openly serve in the military. The pros, cons and my reasoning. Needs to have a long introduction. starting from the past history of it until now. Other foreign military leaders allowing it and Obamas views on it. I am for gays openly serving just needs to be very structured and organized.
