Although you made many more points, this is the one I want to reinforce for all of the people who keep pointing out that it isn't illegal to be gay in America: a man who struggled with his own sexuality due to a society that shamed him for it murdered 49 other people, a mix of gay people and their allies and we watched as people around the country celebrated it. That's why Pride exists. In 2016, it's still possible, even in the enlightened western world, to be murdered for your sexuality.
