Rachel Laser, the president of Americans United for Separation of Church and State, is leading the fight against Christian nationalism in the United States. Laser, who is Jewish, believes that the belief in favoring Christian values over those of other religions poses a threat to religious pluralism. She has faced concerns about her leadership from both within and outside the organization, but has proven that she can effectively work with Christian board members and in coalitions. Under Laser's leadership, Americans United has taken legal action against policies it opposes and has seen a significant increase in revenue.
