how do you guys handle rudeness on these forums ?

I mean you try to help, even though some of the questions are pretty dumb.

You send them links to tutorials, or suggest they read a section in the Help Files.

They'll often reply with venom, suggesting that you are patronising them, or tell you that the tutorial or Help File is crap, and it's all your fault that they still can't get things working.

I'm a fairly patient guy, but just lately I've felt like telling them to go shove it up their ass and whistle Dixie.

How do most of you respond ?
