A newcomer's behavior probably seems appropriate to him/her, and a problem in that regard usually indicates unawareness or misunderstanding of Wikipedian culture. It is not uncommon for a newcomer to believe that an unfamiliar policy should be changed to match their notion of how things should function, especially if they notice that there is already some level of disagreement over the policy in question. Similarly, many newcomers want to have their contributions to articles accepted without question, especially those which pertain to subjects on which they have extensive knowledge. Behaviors arising from these perspectives, while possibly misguided, are usually not malicious and should not be treated as such. Many new users who lack an intuitive grasp of Wikipedia customs are gradually brought around, once the logic behind these customs becomes clearer to them.
