Most people argue and make appeals to emotion not logic.<p>I have noticed this myself.  I think it mostly comes from not knowing what or how to make an argument.  For instance if I state a argument such as<p>Premise 1:  All men are mortal.
Premise 2:  Socrates is a man.
Conclusion:  Therefore, Socrates is a mortal.<p>To refute my argument someone would have to demonstrate how my first two premises or my conclusion was wrong.  Usually everyone just bashes the conclusions but never refutes the premises of the argument.
