This is what a coward, a liar, and a mooch looks like. He used the military to further his personal goals, and now, when the nation needs him, he is turning his back on those who got him where he is now. The press should not be allowed to refer this twerp as a marine. Kick him out, and take back every penny that the military has given to him in college aid.
Then, get rid of conscientious objector status in the all-volunteer military- and for the exceptionally stupid, force all recruiters to tell potential recruits that they just might have to kill someone in the future.

John Scalzi has some trenchant remarks regarding Mr. Funk:
You have to be a really interesting sort of ignorant not to know that the Marines kill people from time to time. Your first hint: The big rifle so many of those Marines carry around. Your second hint: All those movies, books and television shows, widely available to the general public, in which Marines are shown, you know, killing people. Your third hint: The fact that the Marines are widely acknowledged to be a branch of the military of the United States, and militaries are likewise widely known, by most people who are smart enough to stand upright on two legs, to kill other people on occasion (typically members of other nations’ militaries, though sometimes they’re not so picky, depending on country and context).
