No its not rude, and you are very right in this regard that proper titles should be given and rules should be followed. Even I personally never had any conflict with any decision of moderators but at times I feel moderators acting very rudely and in a very bad manner, specially two three moderators. I can just request you to be polite with people. Even there are defined rules and people should follow them, and moderators are to make sure that rules are implemented but still little flexibility and gentle behavior is requested from you. At times after reading moderators posts I feel like reading statements of some SHO.
