Although, after reading some evols on these threads, I do wonder.
There's a difference though when you try to make creationism/ID part of school cirricula as part of your agenda. Certainly, they are entitled to their own opinion. But science isn't a democratic process - what is or what isn't accurate is decided by research, not by vote. And the research points towards evolution.
ID-ists, astrologers, pyramid-and crystal power-sts, homeopaths, Lawsonomists, and so on and so on have the same right to free speech and association, the right to publish, etc, as anyone else. But none of them has a "right" to taxpayer money to try to present their crap in classrooms as though it were science.
