I'm not sure I understand the "direct order" part.
Was he ordered by a superior to delete his FB page, then refused?
Or are you all talking about a standing order regarding personal
opinion, which may or may not specifically prescribe against FB
page content? Just looking for the smoking gun here.
"Stein said his statement about Obama was part of an online
debate about NATO allowing U.S. troops to be tried for the Quran
burnings in Afghanistan. In that context, he said, he was stating
that he would not follow orders from the president if those orders
included detaining U.S. citizens, disarming them or doing anything
else that he believes would violate their constitutional rights."
Sounds like he was describing a what-if situation, which falls far
short of advocating blanket disobedience versus the president.
Now, if Stein was indeed distributing "NOBAMA" stickers, it would
more clearly be a case of engaging in political activity, as well as
technical sedition --more than sufficient grounds for discharge.
