:::::The policy I referred to above:  Which I think is pretty clear that what you are arguing about is contrary to policy.  
 Myth has multiple technical meanings in different fields, and several everyday meanings: 

     * In sociology, it refers to a narrative that is important for a group, and may or may not be true, but is not verifiable. 
     * In folkloristics, it means a sacred narrative that is believed to be true. 
     * In common use, it usually refers to a narrative that is believed to be false. 

 Except in rare cases (e.g., urban myth), the common meaning should neither be used, nor assumed. Do not use the word to refer to propaganda or to mean "something that is commonly believed but untrue".
