We had a secular education system. The Christian Nationalists, who have nothing to do with the teachings of Jesus in the new testament and are often linked to white nationalist racism and bigotry, are forcing a Christianity first into public schools while claiming we are a Christian Nation.

Of course, this is actually the exact opposite of what the bible says to do. Matthew 28:19-20: instructs followers to "make disciples" through teaching and invitation, not coercion. Jesus taught that others will only listen to Christians if they embody the love and compassion of God, gaining the respect of others and opening their mind when they preach the gospel, as opposed to anti-Christ heresy demonization approach of saying there's "invasions" of classes of people that Christians must rise up against, inciting followers into action through hate, fear, chaos and division, rather than peace love and unity, forcing Christianity into government and schools (hate-thy-neighbor anti-Christ values). The bible says only God can judge, and that everyone was created in God's image, there is no male or female, jew or gentile, for you are all one in Jesus Christ.

Once Christianity starts being forced into curriculum, it's understandable Muslims will say ok, but then you have to add some level of education about Islam and other religions to be fair. But the bigotry and hate is the point with these white nationalists.
