After awhile, it will become increasingly untenable and appear unfair and discriminatory to deny and restrict ID on religious or rather anti-religious grounds claiming such ideas have no place in science.
Truth is based on percentages?
How many people believe in homeopathy, dead aliens at Area 51, Bush blowing up the twin towers, psychics, healing moonbeams (my favourite), haunted houses, astrology, wiccan magic, shamanism, crystal healing, levitation, divination, perpetual motion, faces (or more recently Bigfoot) on mars, crop circles, aliens probing cow anuses, vaccines causing autism, vampires, exorcism, flouride in water causing stupidity, bermuda triangle, jewish world domination, the US did not land on the moon, elvis is alive (or is he dead now?), atlantis, no holocaust, alien landing strips in South America, Voodoo, and most important
last tuesdayism.
Sorry if I missed a bunch. The list of nuts is miles long and they are all claiming discrimination from having a place in science.
