Media Matters Rated Left in Dec. 2021 Independent Review

A Dec. 2021 Independent Review by an AllSides reviewer found Media Matters maintained its Left bias.

Media Matters runs advocacy campaigns urging advertisers to drop conservative TV personalities, such as Tucker Carlson and Laura Ingraham. It largely focuses its activism on targeting Fox News. A Media Matters campaign at the time of review, #UnFoxMyCableBox, was an effort to get consumers to tell their satellite or cable TV providers to drop Fox News. On its campaign landing page, Media Matters said that "Fox News lies all the time" and "promotes extremism, fuels conspiracy theories, and celebrates bigotry and racism."

Media Matters took a strong left stance on all issues reviewed, such as stating that right-wing media was "baselessly portray[ing] [Twitter's] decision to suppress a story about Hunter Biden as having influenced the results of the 2020 presidential election." (Background: Read about the Hunter Biden laptop story and the Twitter Files here.) Media Matters takes a supportive stance on gender-affirming care (read about why "gender-affirming care" terminology and transgender medical practices are controversial here.) Media Matters called "climate denial" a "conspiracy theory", and rejected concerns that red flag laws meant to address gun violence would end or harm due process.
