Anarcho-Communism dominant over other anarchies

Sorry for sensitive title , but I seen some people say that Anarcho communism could be the dominant ideology in a anarchist world , that means that other anarchist ideas could be limited or prohibited in an anarchy by Anarcho communist, so that the anarcho communist want only Anarcho communism to be the guiding idea and order of society (or other Anarchist administration, economic , organizing and living and ... Ideas be eliminated)

Now I don't believe in this(since is Anarchism!) but since I'm not a very professional in anarchists arguments , I wanted to know your thoughts.
