User talk:2A02:8084:20E3:A080:2556:883A:F1E5:F2AD

You currently appear to be engaged in an edit war; that means that you are repeatedly changing content back to how you think it should be, when you have seen that other editors disagree. Users are expected to collaborate with others, to avoid editing disruptively, and to try to reach a consensus, rather than repeatedly undoing other users' edits once it is known that there is a disagreement.

Points to note: If you find yourself in an editing dispute, use the article's talk page to discuss controversial changes and work towards a version that represents consensus among editors. You can post a request for help at an appropriate noticeboard or seek dispute resolution. In some cases, it may be appropriate to request temporary page protection. If you engage in an edit war, you may be blocked from editing.
 * 1) Edit warring is disruptive regardless of how many reverts you have made;
 * 2) Do not edit war even if you believe you are right.

You need to read MOS:ERA. Wikipedia does not prefer BC or BCE - either is acceptable, but we maintain consistency within an article, and do not change from one to another without consensus. Do not just keep trying to change to page - start a discussion on the talk page, and try to build a consensus there for a change. Girth Summit  (blether) 22:44, 24 January 2019 (UTC)
