Whichever fucking cunt at Wordpress came up with that filthy Walker class and how a navigation item tree should be traversed, shall be hanged to death.

No wonder Wordpress itself makes no sense at all nor has it any connection to any intelligent lifeform whatsoever.

Edit: This rant does not even closely show how high my fucking rage-level is!
