No, this doesn't represent a change in ideology. It is only a cooperation between different methods to achieve the same goal. Shoot A Liberal is still all about shooting liberals. I am merely here to represent the point of view of those who prefer to impale liberals.
Why impale a liberal, you may ask. Well, when you shoot a liberal, you hear them snivel and beg for mercy until you pull the trigger. BANG, then it's over. You have a nasty bloody mess to clean up. Sure, there's not much work involved, and this method is very effective at stopping the spread of liberalism.
However, when you impale a liberal, they not only snivel and beg for mercy until they are impaled, but continue to beg and cry while suspended in the air from the eight foot pike inserted through their body. This sniveling could continue for days depending on the chosen point of entry. And impalings are scalable. Once you have impaled a dozen or so liberals, you have your very own Forest Of Woe ©. It serves as a wonderful public spectacle, and an effective deterrent to the future spread of liberalism.
For you urban imaplers of liberals, I am working on the Chiatops Pet Of Woe ©. It can be placed in an apartment where space is limited. You could set it outside on a balcony, or on a window sill. I haven't worked out all the kinks yet, but when I do, it'll be on sale at Amazon.com.
