Philosophers and argumentation theorists have increasingly argued that certain types of ad hominem arguments are not inherently fallacious and can sometimes be logically legitimate.
The retrieved papers feature several philosophical works (such as Johnson 2010, Tindale 2008, and Cohen 2015) arguing that ad hominem arguments can be legitimate rather than strictly fallacious under specific conditions (such as virtue epistemology or evidentialism). Therefore, the claim is supported by the literature.
