[1] She cofounded the advocacy group Ex-Muslims of North America (EXMNA), which seeks to normalize religious dissent and to help former Muslims leave the religion by linking them to support networks.

In a 2017 interview with the blog Gene Expression, she said of her religious participation: I dressed modestly to deflect attention from my body, and to the bemusement of my parents, I chose to don the hijab for a short period.

[1] EXMNA believes Muslim communities often shun those who are accused of apostasy as well as their families and that fear of excommunication and violence makes it dangerous for closeted ex-Muslims if they are exposed as disbelievers.

This is the reason why EXMNA believes that it is very important to normalize dissent in religious communities and why they have created a network of social support for those who chose to leave Islam.
