I think any outside culture has the potential to be a positive force for Christianity. There is no witnessing if there is no one to witness to. There is no being a light without some sort of darkness.
What outside culture? What specifically? When I identify Islam as a corrosive force to Christianity or secular liberaldom as a corrosive force it is from the position of an observer, seeing things from a historical advantage.
This should be obvious with regards to Islam because historically Islam whenever it has been in a position of dominance never let Christianity or the infidel thrive. They kept the people of the book in their dhimmi status and told Christians if they tried to convert a Muslim to the faith, they would execute them. Islam, unlike western Christianity, has not shed it's fundamental religious character hence why the emergence of Islam in the west is corrosive.
With regards secular liberalism. How can it be argued that since the enlightenment the Church has not only ever been in retreat? Christianity is the not the guiding force of the west any more and why should we expect it to thrive in the current conditions it faces? You want to blame a specific conservative subset of Christianity as the leading cause in the USA, namely Evangelical conservatives. Yet it goes beyond any criticism of that community (and I have plenty) to the wider social order. IN a society which encourages individual liberty and praises it and makes it the rule, Christianity being a norm is impossible. Because Christianity has at it the idea of a social contract between it's members. This is why one of the only groups growing are the Amish, despite any flaws you can attribute to them.
When you open the door for practices which were regarded as immoral only a century ago and give wider and wider permissiveness to practice them, as secular liberal democracy does, why be surprised at how this corrodes Christendom in the west?
I don't know why you think I blame conservative churches alone.
Mainly because you seem more concerned with them and never mention the liberal Churches which engage in politics.
Still, why is this a bad thing inherently for the Church or Christians to be politically active?
But if the concern is decline in church attendance, they're the ones who make up the bulk of church attendees in this country and, thus, are the ones with the most numbers to lose. They're also the most vocal and most culturally and politically influential. IOW, the mainline denominations are already irrelevant and, outside the black community, the black denominations were never relevant. The only denominations that have the ability to turn people off in large numbers now are the ones making the most noise now - and that's the evangelical / fundamentalist / charismatic groups.
It goes beyond just Church attendance to the whole of our society and what we are immersed in. Can it be argued that we live in a Christian culture in any western country? That we have positive forces that seek to reinforce our faith? You might say that's what it means to live in a secular democracy but that's part of the problem of why Christianity has no appeal to the masses of young people today. They are awash in a progressive culture, not a Christian one.
There's nothing inherently Christian about "traditional ways of living and retaining the past." There are many things from the past that should be discarded. Hanging onto something merely because we've always done it is arguably a step towards idolatry.
I was describing conservatism and how it wants to retain a religious identity rooted in tradition and the past. Not making an argument for it, though I believe that to be the wisest course. I understand why you as a progressive Christian would not accept the historic standards of Christianity.
Racial attitudes are a good example. Conservative Christian groups have a long history of supporting racist ideas and practices and of resisting progress on those issues in greater society.
Isn't it the left who argues that blacks should get preferential treatment to bring about equity?
I also find it hilarious that the first thing the leftist appeals to is racism, as if people on the left had not been historically racist. But hey, if you think this is just an excuse to boost racism, feel free to think that.
The whole MeToo movement is about a form of sexual restraint.
It also lead to people being accused falsely and unable to defend themselves. The sexual ethics on the left are unable to deal with metoo effectively because they don't understand human nature and the restraint one must put on one's life. I recall Mike Pence was criticized for not meeting with women alone because it would deny them opportunities, yet his rule prevents the sort of thing we see with men who are less controlled.
Still, would you not support the sexual revolution more broadly? No fault divorce, inappropriate contentography, sex outside of marriage and the like? If not, why not?
I never claimed anybody advocated "completely overturning the USA." But it's not uncommon at all for advocates of certain policies (restrictions on LGBTQ rights comes to mind) to be guilty of attempting to foist rules on the rest of society that are entirely religious in nature.
Actually none of the people I listed advocate for restricting the individual freedom of the homosexual to do whatever they want. Which is part of the problem and why the right continually looses the culture war.
Have you ever listened to a widely respected Conservative commentator?
