it's a debate tactic showing how the the assumption is abusive.
Ummmm, noooooo, the assumption in this case is not abusive it's true. So far ID is not science. If you can provide scientifically peer review papers that provide a falsifiable ID hypothesis with supporting data and if other scientists can replicate the results, then I will back down and agree that there may be some scientific validity to ID. But as yet no-one anywhere has done so. So, for the time being ID is unscientific, period! That is not abusive that is just science, deal with it. Maybe if you goto a major university and start doing science this will all make sense to you.
