Interesting. Well, this particular Christian has never, does not, and will never believe in a "sprinkle baptism." In fact, I have never visited a Christian church where this was the method of baptism.
Since baptism is an example of dying and being risen again, sprinkle baptism doesn't hold to this notion at all. If one dies, he is buried. Therefore, the complete submersion of the body into the baptismal water. Then, he is raised from the "dead," which is the total coming out of the baptismal water.
I'd be interested in knowing which Christian denomination(s) you are referring to here.
Anglican/Episcopalian, of course ('s what I said :-)
I can overlook differences in methods of the baptism ceremony itself, since I do not believe physical baptism to be salvific in nature. Getting dunked or getting splashed or sprinkled, all are in some sense symbolic declarations of what has happened to you in Christ. However KJV's creation of a new, specialized word for "immersed" -- in my opinion -- robs other scripture verses of the impact they could have in English translation, such as references to baptism in the Holy Spirit.
