Edit warring
Please note that repeated attempts to remove sourced material from articles is likely to be considered to be edit warring, which may result in your being blocked from further editing of Wikipedia either temporarily or permanently.  If you try to make a significant change to an article, and somebody else reverses it, the appropriate thing to do is to go to the talk page, have a reasoned discussion, and try to come to a joint view of what is the best way forward for the article (see WP:BRD).  Merely trying to ram through the change you want to make by altering the article again and again is not acceptable, and will lead to sanctions being applied.

For the moment, the article Haplogroup O-M176 (Y-DNA) has been locked for two weeks, so that no-one may edit it.  If you sincerely believe that there are issues with some of the material being presented, please discuss your concerns on the talk page, and try to find an acceptable way forward.  Note, however, that WP exists to make accessible material that has been published in what it considers to be reliable sources.  If the material appears significant and relevant to the article, and has been published in a legitimate academic journal, normally one would expect to find it included in the article.  Even if the material is questionable, if it is in wide circulation and often presented in discussions of the topic, then on those grounds alone it should still be included.  If there are good grounds for questioning the material, those grounds can be discussed in the article  but note that they must reflect the position of reliable sources that have been published and can be referenced, not just your own personal beliefs, knowledge, or unpublished research. (See WP:NOR for more information).

Sorry if this seems heavy-handed, but in 10 years evolution of Wikipedia these principles have proved to be a key foundation for building stable and improving articles that everybody can contribute to.

All best,
