Melanie Phillips is providing insight from the British side of politics:
The challenge for conservatives on both sides of the pond is to find a way of conserving the essential values of Western Civilization and defend them against the onslaught being mounted against them both from within and from without — but to do so in a way that is generous and big-hearted rather than narrow and sectarian, and embraces rather than repels.
Ah, there's the rub. No matter what you propose about Conservatism, someone will feel slighted and left out, disenfranchised or marginalized. You can't put forth Conservative principles while pandering to the me-first fears of folks who like to live outside the so-called Conservative norm.
Nevermind that you don't care what folks do in their bedrooms or with their leisure time and money, if you don't actively build it up as Important, you will scare away certain fiercely independent individuals who center their entire identity on being Who They Are. It's another subtle victory for the Left, another fear-mongering that has been ingrained. You will lose your Self!
So you either must decide to include their narrow agenda, which feels nice to do, but if it pulls apart the Central Ideal, you will lose focus. You can try to woo the fiercely independent types but you can't depend on them. They are extremely valuable if they too, can make a bit of a sacrifice for something better.
The very nature of Rugged Individualism dooms the Republican Party in a post-modern age. And the Rule of Law has been supplanted by Situational Ethics... which were taught to you by very good teachers who were excited by this new educational tool. What is right? It depends.
Such a subtle, insidious little fox has corrupted what was so simple and pure: Right and Wrong.
Who are you to say what is right?
You have no answer to that, because we no longer agree on Absolutes. Even within our own party.
Relax and let the Left's victory do its work. As a Republican, you can embrace the deconstruction of your Party and the mockery of your Ideals, and look around at the pieces and find what is worth salvaging and what you will fight for.
The Republican Party has become an old woman who is motivated by fears of how it is perceived, now that its best days are past. A bit more of this, that, and the other will somehow "youthen" what is hopelessly out of touch and beyond repair.
Let it go.
