Obviously the most avid creationists want the two theories taught side by side because creationists know its pushing the limits of reason to say creation science is as sound a science as evolution. Knowing that creationists abhor everything about evolution because evolution is contrary to their personal and singular views of the Bible, it then becomes obvious that the end-game really will be to replace evolution with creationism. Creationists just want acceptanace now. Later it will become some sort of skewed "truth" at the expense of the health and standing of American society as we know it.
There are all sorts of shades of variance in how much evolution creationists believe in (from belief in the evolution we ALL know is fact within species, to God created a blob and let it go on its own).
There is no one group plotting to replace the teaching of evolution.......except perhaps in your imagination.
As I said.....this thread has been an education. A little paranoia, fear, and hyper-sensitivity, and mockery, mixed in with a stellar defense of 'objective' and 'unemotional' science..........LOL! Very interesting, indeed.
It's the "ugly girl" syndrome, writ large: everybody knows about the fat, ugly girl who can't get into the disco by herself, so she pals up with a hot looking friend to get access. She really hates the good-looking gal, but knows that she's her meal-ticket to get into the party.
It's all about access, and "teaming up" with Evolutionary theory is Creationism's way of getting into the party (classroom). And, just like the fat, ugly girl, both despise the one who got them in the door.
