Every day of our lives we see ideologies at work. These systems of beliefs are found in countless mediums in all sorts of common situations. Within ideologies are images, values, beliefs, and other principles that make up guidelines that publicly portray private ideals. One medium that encompasses all factors of ideologies are that of bumper stickers. When we see bumper stickers, we are seeing an ideology being publicly portrayed within limited contexts; limited contexts include images, word count, color, etc. Bumper stickers have a small amount of space and time to engage an audience; the sticker may be stuck to an individual’s bumper for as long as the person has the vehicle, but another person driving behind the car has only a small amount of time to see the ideology being displayed, decipher its meaning, and immediately choose a side, agreeing with the bumper sticker ideology of opposing it. As Michael McGee states in his article featured in The Quarterly Journal of Speech, an ideal ideology must contain the isolation of society’s ideographs. When one ideology is isolated, it will be publicly critiqued and privately upheld. An example of this isolated iconography is that of the Jesus Fish. This icon of Christianity was created for an initial meaning. Now, other groups with opposite meanings of the symbol-such as Darwin-ists, or evolutionists-have took the Jesus Fish and added legs to the original body to represent fish “evolving” legs. The tension that is the product of these two opposing ideologies, within in a given environment, is nothing short of rhetorical discourse. It can be drawn from the overarching discourse of the icons that the original Jesus Fish becomes a frame for the modern-day interpretation of the fish symbol. The Jesus Fish symbol has a starting point that is a constant in the ideology of religion and the eventual emergence of Darwinism. “… at any specific “moment” to be a consonant, related one to another in such a way as to produce unity of commitment in a particular context.” (McGee, 16) As the iconography switched within certain groups and organizations, the historical context of the Jesus Fish symbol is still retained through its presence even in a conflict of ideas.
