re: "free speech" -- the first amendment to the constitution says, "Congress shall make no law..." What it doesn't actually say is, "random poster shall not respectfully ask for decorum..."
You certainly don't have to do anything I ask you to, but I would think that if you'd been in the military you would understand the concept of separating the way you treat the office of Commander in Chief and the man
who currently holds the office. If you want to go pee all over +Barack Obama
's feed, with pro-Romney blurbs I won't say boo, but regardless of who I'm going to vote for in November (and given that I don't know, I'm quite certain that you don't), I think it's disrespectful to the nation
to do so in the White House feed.
