Consistent compliance with Wikipedia policy is more important than your personal beliefs. Inconsistent compliance is a good sign of activist editing.
For example, if you assert something, and are presented with countering evidence from a reliable source, do you consider changing your position like a reasonable editor, or do you ignore it to argue your position?
When you join a wiki community, be a constructive editor.
Wikipedia is currently fighting a war on vandalism. Wikipedia is vandalized many thousands of times per day, with most of these occurrences corrected within minutes or even seconds. This requires many volunteers in an organized effort to repair this damage. The Wikipedians on the front lines of this battle are the members of Wikipedia's intrepid Counter-Vandalism Unit (CVU). The CVU has developed specialized tools, procedures, and initiatives for fighting vandalism on Wikipedia. You can be of great service to Wikipedia by joining the CVU.
