Identified as one of the largest resistance movements of the 20th century (Ortner 2013, p.530), feminism has achieved significant benefits for women on a global scale. Feminist activism has been successful in achieving its many goals for women (Ortner 2013, p.530), particularly challenging gender equality and the oppression and subordination of women around the world, improving opportunities of participation in education, workforce, political and economic environments (Bruns & Kaschak 2011, p.1). However, despite the achievements of the women's liberation movement in the 20th century, feminism today is widely perceived to be in crisis, with postmodern ideas challenging its fundamental assumptions and an increase in apathy and defensiveness towards of liberal feminism (967).

Regardless of post-feminist claims of equality achieved and sexism consigned to the past (Gill 2014, p.522), Western women remain unrepresented and subject to gender stigma, inequality and violence. Contemporary views are victimizing women, with individualization depoliticising the fact that women continue to suffer from gender inequality (Dosekun 2015, p. 960).

This introduces the fourth wave of feminism, which incorporates the Internet as a form of activism, protesting against sexual violence, profiling and "slut-shaming" (Reger 2014,
