Fallacies do not in and of themselves disprove an argument - but I usually see them as a barometer for the quality of discourse and the character of the person making the argument. An argument strongly compromised by fallacies, made by someone otherwise intelligent, suggests to me disingenuity and intellectual dishonesty - and it affects how willing I am willing to engage in debate in return.
