Ad hominem does not reach the level of a valid scientific objection.
A double standard?
You are projecting again. I accurately call God haters and Christophobes "God haters" and "Christophobes" because they engage in God hating and Christian fearing. That's not an attack against God haters and Christophobes, that is describing motive and an underlying agenda for the current venom towards those who subscribe to intelligent design.
Another way of putting it is: "Examining and drawing conclusions from the evidence." If we were to discuss taxation, or the best ski lodge, it would take a particularly antisocial clod to engage in the routine and apparently required lying, pandering, insults and hate speech typical of the left evolutionists/materialists. Now why is it required for evolutionists/materialists to single out Christians (not Jews, Muslims, secular critics of evolution et al) for all of your frustrations?
Number One, the Bible says that you folks will do exactly that. Number Two, history demonstrates that you folks will do exactly that. Number Three, the balance of posts by the materialists demonstrates that this is an unending pattern of behavior. We can look at your posts, and the variety of self-proclaimed atheistic theologians (there is an oxymoron for you) who feel completely qualified to describe and characterize a religion they know very little about and have every reason to ridicule.
When discussing origins, exactly how is the phrase "Junk Religion" supposed to be informative and constructive in a debate? "Junk Science" is appropriate because it is the type of so-called "science" that is implemented to muddy the waters concerning true origins. Global Warming has more basis in evidence than Oort Clouds, yet materialists say "science has proven it". Oh really? Absent any evidence, we have elevated speculation to fact? That is called "junk science".
So this bravo-sierra about "Ad Hominem does not reach the level of valid scientific objection" is nothing more than a cloud to hide the fact that your ilk's stock in trade is Ad Hominem and junk science. Accusing others of engaging in what you regularly do is called hypocrisy.
Get used to the label, it fits materialists like a glove.
