Biden was making ad hominem attacks against Donald Trump on the day that he instituted travel restrictions. The “fact checking” has labeled Trump’s tweets that Biden called him Xenophobic for the teavel restrictions as mostly false because it was an ad hominem attack against Trump that did not mention Trump’s policy.
Ad hominem attacks are an illegitimate form of argumentation because they are without substance and they fail to address issues.
“Ad hominem attacks are an illegitimate form of argumentation because they are without substance and they fail to address issues.”
But they can be effective, so people keep on resorting to them. My reaction to them, when I see them on FR and elsewhere, is that the person resorting to them realizes that they just lost the argument.
