I think that runs counter to how the Church has spread through history. If all the martyrs blood could have been spared through dialogue and concession, you'd think the saints would have taken that option.

It is not foolhardy, our lives on this world is a pilgrimage not eternal. When you check into a hotel do you start redecorating buying new furniture? This life is merely a stop on the way to Christ, not the destination.

We need to push back against secularism not conform to it, if the early Christians had conformed our faith would not be as given by the apostles.

As for the political effectiveness of persuasion I am somewhat skeptical. How often in your life have you seen someone online or otherwise being persuaded?  People tend to be stubborn unless they are predisposed to agree with you.
