Personal Bickering is diluting the threads. In some cases, half the posts are bicker posts. It makes for a slow, boring thread read. Now I embrace the hard-hitting, offensive political insult. It makes for good reading. See Dan Loney and Ian McCracken for examples. But I'm simply going to bin (delete) all the weak non-political bickering. No warnings. No explanations. And if I feel you're overworking my moderator skills, I'll card you.
