This attitude is exactly the reason why the American government is so unproductive and uncompromising: people do not look at the value in others' ideas; rather, they revert to childish attacks on their "opponents'" persona, which just causes further tension.<quoted text>
Wiki - Ad hominem: http://en.wikipedia.org/wiki/Ad_hominem
"Doug Walton has argued that ad hominem reasoning is not always fallacious, and that in some instances, questions of personal conduct, character, motives, etc., are legitimate and relevant to the issue, as when it directly involves hypocrisy, or actions contradicting the subject's words.
The philosopher Charles Taylor has argued that ad hominem reasoning is essential to understanding certain moral issues, and contrasts this sort of reasoning with the apodictic reasoning of philosophical naturalism.[14"
And one man's evidence is another man's irrelevant gibberish. Evidence is judged in courts of law but in discussions on a blog, evidence becomes very subjective.
So no select committee decides the fallacy of your ad hominem except for the one-man committee of Doug Walton you mean? Talk about "hypocrisy." Yes, I realize that evidence is almost always biased, which is why I am allowing you to find "evidence" in a site that shares your point-of-view, FOX. You obviously just can't find any evidence... not even in your Republican-supporting FOX news.
