The corrolary to Hanlon's Razor:
"Any sufficiently advanced incompetence is indistinguishable from malice."
Not a problem, as long as you stick to the main law. You don't have to distinguish between jerks and fools, just offer the benefit of the doubt. (And how pleasant it is to feel charitable when thinking "This person is completely incompetent)! I think Hanlon's Razor may be my most important life tool. As in, if I forget it, I'll likely do something that ends with me serving a life sentence.
Yeah... More than once I've looked at a person and thought, "That SOB is going to be the reason I end up in jail."
