Value, respect, and strive for diversity in editors

Verifiability isn't a paper tiger or you can count the whole English wiki unsourced BLPs drama as a non-event.

And there is the Verifiability scorched earth tactic.

You have a "grudge" with an article that ended with a no consensus in AfD, tags fews unsourced facts with the local wiki "citation needed" tag variant.

Wait a week or two if the facts are still unsourced remove them. Repeat the two steps again and again until the article is completely botched and the closest thing to an empty husk.

People can fight as much as they want over articles, it's not much a problem. However if such conflicts expand over contents using Verifiability as a weapon of mass blanking then we will have a hell time.

Yes, a completely unverified article can be scratched; my point is, no one ever goes to a contributor's talk page and tell him that if he keeps entering unverifiable data "you will be blocked from further editing" and so on. And many completely unsourced articles do remain (I'm not saying that's actually a bad thing, btw, just that different policies have very different levels of enforcement and these aren't indicated to the new user).
