This is both a political and an ideological battle. It has already happened in some segments of American Christianity where it may give the appearance of having been all consuming, but the fact of the matter is that those who have already done a lot of the ideological battle, which includes Baptists going back to the slavery debate, the fact of the matter is that the opposition on the left has a sound, solid, well-reasoned, well-articulated message that guts the core of the pseudo-religious MAGA cult. Their interest is holding on to freedom, understanding that if some people are not free, then no one is free, and that in order for them to have religious liberty and freedom of conscience, everyone has to have it. The idea of loving one's neighbor, within the theology and practice of any legitimate Christian faith, is unconditional, and it does not exclude anyone, even those who may, because of their own conscience, reject any kind of Christian practice. The important steps to take are to unite in opposition to the attack on freedom, not merely to defend one's own turf,, but to defend everyone's freedom.
There is a lot of strong, solid messaging against the intrusion of white, Christian nationalism, Project 2025 and the whole phony pseudo-Christian veneer of right wing extremist politics mixed with right wing religion in Baptist News Global which is produced by the Associated Baptist Press, that is of benefit in helping to identify the non-Christian elements of MAGA.
