Even Darwin explicitly stated that it was simply a theory; not a proof. Until something better came along. To say that "Evolution" as argued today has been proven scientifically, but ID has not, is to simply attempt to not derail the discussion. ID does not claim anything as proven either, nor seeks to ban the teaching of evlolution. It seeks simply to be given a voice.
On the other hand, the reverse is not true, due primarily to the Gay agenda.
The isn’t maths. Maths deals with proofs - not science.
The same crowd that believes the global warming lie and there simply is no room for discussion is the same crowd that projects on and on about this idea of “IDers” crushing free speech.
Liberalism is clearly a disease.
Ouch!
Beware that the informal meaning of the word "theory" is the opposite of its scientific meaning. While the informal meaning suggests that an idea is merely guesswork, the scientific meaning indicates that an idea has indeed held up to the rigor of scientific-method experimentation.
So your note about what Darwin said about evolution can reasonably be construed to mean that evolution, particularly macroevolution, is scientifically tested fact, which it is not.
Consider the following links which show the contradictory definitions of theory.
http://en.wikipedia.org/wiki/TheoryGiven these contradicting definitions of theory, is it any wonder that creationism versus evolution discussions seemingly go in endless circles?
