Alabama National Guard to soldiers: Keep your thoughts on Democrats, guns and Barack Obama to yourself

Classification: Unclassified
Caveats: None
[Unit Redacted] conducted a social network brief during the Jan. (Inactive Duty Training.) The ideas, do's and don't's, what can and cannot be posted, were explained in what I believe was a very elementary level. When asked if anyone had any questions, comments or complaints, no one raised their hands. I made the assumption that there was a clear and concise understanding concerning everyone's actions and responsibilities. Apparently I made a miscalculation in my assumption. Here it is again, for the last time.
Update personal status, ie "at the mall"
Comment on friend's status, ie "happy birthday"
Comment or add posts concerning gun control, the Democrats, the President, Congress, or personal opinions about state or federal government matters.
What you do on face book, twitter, or anything else that is available to the public is a direct reflection on this unit and you as a soldier. If you have a question about a post, give me a call and I will let you know if it violates anything. This also includes "likes" post on other friend's pages. I do not care or want to hear about someone from another unit outside the (unit redacted.) My concern is with members (unit redacted) and (unit redacted.)
By all means have fun with the networking, but stay away from volatile subjects. Don't be that guy.
