As of one minute after midnight on 20 September 2011, gays and lesbians are no longer discriminated against by the United States military. The us joins 42 other progressive nations that allow gays to serve, including Israel, Japan, Russia (!), and almost all of Europe.
In most of the United States, gays and lesbians are still second-class citizens. We can marry in only six states. Employers can legally fire people for being gay. There is still a long way to go.
But the end of DADT is an important event in ending discrimination against LGBT people. We have President Obama to thank for this, and we owe him our continued support.
