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.
When asking a question about editing Wikipedia at the Teahouse or Help desk, please include all the facts needed to answer your question - especially the page title you're enquiring about. Most respondents will assume you are editing in 'desktop' view, and are using Source Editor, not Visual Editor (VE). So remember to say if you're working on a mobile or using VE.
Always give context to any question. At the Reference desk, for example, don't ask "who was president in 1900?" without mentioning the country you're interested in! This prevents volunteers helpers having to ask follow-up questions before providing answers. Friendly reminder: the Teahouse (for new editors) and Help desk are for questions on how to use or edit Wikipedia; the Reference desk is for questions about anything else (real world questions).
