Mac Donald refers to herself as a secular conservative. She has argued that conservatism is superior to liberalism by virtue of the ideas alone, and that
religion should not affect the argument and is unnecessary for conservatism. Mac Donald maintains that conservative values like small government, self-reliance and liberty can be defended without "recourse to invisible deities or the religions that exalt them." and has advocated positions on numerous subjects including
victimization, philanthropy,
immigration reform,
crime prevention,
racism,
racial profiling, black incarceration,
rape, effect of two parents on crime, and matters pertaining to cities According to Mac Donald, under American immigration policies, the United States has been "importing another underclass", one with the "potential to expand indefinitely." In another private correspondence with Claremont Institute affiliates, Mac Donald criticized
Peter Thiel's
gay marriage (placing 'marriage' in
sneer quotes), mocking Thiel's husband and saying that Thiel's outside boyfriend who had recently committed suicide showed that gay men “are much more prone” to
extramarital affairs “on the empirical basis of testosterone unchecked by female modesty.” During the
COVID-19 pandemic, she criticized March 2020 shelter-in-place policies as "unbridled panic". She argued in March 2020 that COVID-19 would have a similar casualty rate as the
flu, despite public health experts saying otherwise.
Policing and national security Mac Donald has been described as "pro-police". She has been a vocal critic of
Black Lives Matter. During the 2016 presidential election, she described a speech by
Donald Trump on criminal justice as "a radical, bold, and important change of course in the prevailing discourse about policing and crime." She is an outspoken critic of
criminal justice reform, such as the
Sentencing Reform and Corrections Act, which she testified against in October 2015. She has spoken out against no-racial-profiling programs for the police, calling them a "politically correct ignoring" of what is known to be the "logical necessity of Islamic terrorism." She has criticized efforts to instate no-racial-profiling policies, calling these efforts an "illogical tautology" because "you cannot be an
Islamic terrorist unless you're a member of the
Muslim faith". In September 2019 congressional testimony, Mac Donald cited a July 2019
PNAS study on the races of police officers and civilians who are shot, which purported to show that there was no racial bias in police shootings. However, the study that she cited has been corrected, and the editors of the journal wrote that the study was unable to support any conclusions about racial bias in police shootings. ==Reviews of her books==
