Okay, here are some ideas to consider.
(1) We’re in a war. Not a shooting one, but a struggle that has all the other aspects of ‘real’ war.
Now, in a war, one thing you want to do is to try to divide your enemy. Look for disagreements and contradictions within the enemy camp, and try to exacerbate them. See if you can bring some of your enemy’s supporters over to your side, or at least into a posture of neutrality. In a crude sense this is what American elections are about: Left and Right try to win the votes of the Center.
(2) Most people who are secularists are also political progressives. We’re unusual. But because we are secular, we have a chance to reach and influence other secularists who are not (now) conservative, in a way that religious conservatives do not.
People don’t arrive at their political views, and do not change them, on the basis of cold logic alone. Secularist progressives who begins to doubt the wisdom of their Leftist beliefs is more likely to begin to abandon them, if they know personally some secularist conservatives.
(3) There is a split opening up within the secular progressive community. This split is basically between those who believe in the existence of objective truth, and those who do not. The latter subordinate truth to their leftist political goals.
This is not a new development. Over thirty years ago, the Portland Oregon school board began teaching Black children that they were the descendants of ancient Egyptians who flew around in gliders and had psionic powers. But now this tendency has grown much stronger.
There are progressive secularists who are resisting this tendency. We should follow this fight closely and try to take part in the arguments. We have a chance to pull some of these people in our direction.
Exactly how to do this is something we should discuss.
