 Even informal logicians may assume an equality among arguers that is more ideal than real and that may obstruct political progress. The problems that feminists find with assumed equality may be most visible in accounts of ad hominem arguing. Both feminist (Janack &amp; Adams 1999; Yap 2013, 2015) and not-specifically feminist (Walton 1995) argumentation theorists recognize that appeals to the person may or may not be fallacious. The difference is that while the informal logic analysis informs an audience about the irrelevance of a personal attack, a feminist analysis also maintains that the line of reasoning may still succeed because of unconscious biases such as implicit sexism and racism that feminists find unacceptable. For this reason, feminist critiques of ad hominem arguments require more than logical analysis and also consider the epistemology of testimony (Yap 2013).
