> It is tedious because you must edit with facts, not ideology.

Not just because you must edit with facts. If your opposition outnumbers you and/or they have more energy to spend than you, they can grind you down with bad-faith arguments and questions for clarification.

The way this goes is that they edit an article to insert their POV. You edit/revert it. They open a talk page discussion about the subject. Suppose their edit is "marine animals are generally considered cute throughout the world" with a reference to a paper by an organization in favor of seals. You revert it by saying this is NPOV. They open a talk page question asking where the organization has been declared to be partisan. Suppose you do research and find some such third-party statement that "the Foundation for Animal Aesthetics is organized by proponents of marine animals". Then they ask how this third party is accurate, or whether "organized by proponents" necessarily implies that they're biased.

This can go on more or less forever until someone gives up. The attack even has a name on Wikipedia itself: "civil POV pushing". It works because few Wikipedia admins are subject matter experts, so they police behavior (conduct) more than they police subject accuracy.

Civil POV pushers can thus keep their surface conduct unobjectionable while waiting for the one they are actioning against to either give up or to get angry enough to make a heated moment's conduct violation. It's essentially the wiki version of sealioning.

In short, a thousand "but is really two plus two equal to four?" will overcome a single "You bastard, it is four and you're deliberately trolling me", because the latter is a personal insult.
