Yes, you certainly can.
Regardless of your long winded rambling, I have still yet to see any scientific evidence, presented by anyone in any capacity by either side of this debate, or in general, that adding sodium chloride to an aquarium at the dosage levels recommended here has the capability to kill the ich parasite, Ichthyophthirius multifiliis. Going on a rant about how science is unreliable and dismissable at best might be appropriate in a discussion of the scientific method, or the foundations of logical ethics, experimental design, etc., but dismissing the nature of the beast does not thwart an opposing argument.
It saddens me greatly that ignorance, for lack of a better word, of the nature of "facts", empirical evidence, and the dangers of conjecture are so readily perpetrated and accepted within a community that as a whole does nothing more than observe a contained set of defined biochemical processes. If there really is no room for science here, perhaps we should all start curing Ich by praying to the heathen gods and sentencing overstockers to eternal ****ation by the Great Aquarium Overlord.
Science is not a cult trying to convince you that it knows all the secrets of life - science is education, deduction, and logic par excellence.
Perhaps next time this debate pops up in a new thread, it won't end so poorly.
