Final answer:
A common belief of radical feminists is the need to dismantle societal patriarchal structures to achieve gender equality, and they often focus on revolutionary changes rather than gradual reforms.
Step-by-step explanation:
A common belief of a radical feminist is that there is a pervasive patriarchal structure in society which needs to be dismantled to achieve true gender equality. Radical feminists tend to focus on the systemic nature of gender oppression, and may advocate for revolutionary changes as opposed to gradual reforms. They see the traditional family structure and gender roles as inherently oppressive, and often aim to overthrow these societal norms. An example of radical feminist activism was the protest at the Miss America Pageant in Atlantic City, where participants targeted symbols of traditional femininity and critiqued the pageant's racial exclusivity.
