I have been contributing with high quality material to Wikipedia for the past five years and am well aware about its WP OR policies If you did not agree with my usage of the CN tag or formulation of the disputed paragraph I invited you for a debate at the talkpage of the article Now you instead respond by posting me a warning about potential edit war which I consider to be very unpolite I already agreed with you that we need to find a source for the unsourced part of the paragraph but argued it was best to keep it temporarily as part of the article with a CN tag in order to invite for a collaborative work for any wikipedia editor to help finding the needed source Wikipedia Citation needed proof this is an instrument we are allowed temporarily to use at Wikipedia until we succeed finding the needed additional reference for the material and if this is not the case you are allowed to remove it after 1 month Best regards
