Thus the very fine line mentioned. As Spenser Rapone learned being a member of the Communist Party is perfectly legal but not suitable for military service. Gary Stein was booted from the Corps for posting anti-Obama stuff (today a Marine can “like” a political social media post but may not “share” them). I agree with you entirely, but line is still there and for good reason.Depending on the group, “affiliation” may be bad enough.
