Can an argument be both valid and fallacious?

A fallacious argument is often plausible. It is never valid. fallacies are deceptions used to manipulate perceptions. They can sometimes be misunderstandings or mistakes of fact, but one fallacious by their Words and deeds are hardly innocent. The plausibility of fallacious arguments is merely the well crafted plot of their deception. They make their lies plausible by regurgitating facts, factoids, hearsay arguments, shameless appeals to authority all projected with an air of authority so that their intended victims might demurely defer to the superior debater. Examples of fallacious arguments are: George Bush arguing the threat of WMD's in Iraq. Plausible, not valid. Parents don't have the right to home school their children. This fallacy isn't even plausible. Rights are granted by governments. Plausible, not valid. HIV causes AIDS. Plausible, unable to validate. Individual gun ownership is the greatest threat to world peace today. Not even plausible. The welfare state and a rigorous war on poverty will lift the poor out of poverty and into affluence. Not even plausible. Driving is a privilege and not a right. Not plausible yet people not only find it plausible, some will actually engage in fallacious arguments of their own defending this lie. There are no absolutes. Not plausible. The truth can not be known. Not plausible. All are fallacious arguments, none are valid.
