Are We Abandoning the Shamrock?

Around St. Patrick's Day in the last few years, I have noticed in some instances the replacement of the three-leaf shamrock symbol with the four-leaf clover. Since the shamrock is linked in the popular imagination with the Christian doctrine of the Trinity, is this yet another example of some in general society dismissing a Christian symbol? As an Irish-American Christian, I have also asked myself -- is this cultural phenomenon something I should be concerned about?

Before I begin this discussion, I should point out that the legend that St. Patrick used the shamrock to illustrate the Trinity is not true and is a relatively modern legend (see my Baptist Press article, "Baptists and St. Patrick" in 2008, http://www.bpnews.net/bpnews.asp?id=27634).
