How to stop redirecting to login page

So, I have a login link in the corner of my homepage which I want people to click on to login... pretty simple. Problem is that I cannot seem to view my homepage as I am automatically redirected to the login page. This causes issues when you login since the login returns you to the initial page (the home page) which then transfers you back to the login etc. Inf loop time. So I cannot seem to figure out why it is automatically redirecting my homepage to the login page. Thanks.

And here is the login function in the user controller:






    function login() {
        //-- code inside this function will execute only when autoRedirect was set to false (i.e. in a beforeFilter).
       
        if ($this->Auth->user()) {
       
            //Write out the cookie if we are supposed to remember the user
            if (!empty($this->data) && $this->data['User']['remember_me']) {
                $cookie = array();
                $cookie['username'] = $this->data['User']['username'];
                $cookie['passwd'] = $this->data['User']['passwd'];
                $cookie['expire'] = strtotime($this->cookieTerm);
                $this->Cookie->write($this->cookieName, $cookie, true, $this->cookieTerm);
                $this->Session->setFlash('Cookie created. It will expire '.$this->Time->niceTime($cookie['expire']));
            }

            $this->redirect($this->Auth->redirect());
        }
       
        //Auto-login from cookie if user data is empty
        if (empty($this->data)) {
            $cookie = $this->Cookie->read($this->cookieName);
            if (!is_null($cookie)) {
                $this->Session->setFlash('Logged in from Cookie. It will expire '.$this->Time->niceTime($cookie['expire']));
                if ($this->Auth->login($cookie)) {
                    $this->__addDomainInfo();
                    //  Clear auth message, just in case we use it.
                    $this->Session->del('Message.auth');
                    $this->redirect($this->Auth->redirect());
                } else { // Delete invalid Cookie
                    $this->Cookie->del($this->cookieName);
                }
            }
        }
    }
