"Liberal politics destroyed the thriving Christian churches in Massachusetts."
How. How is a political ideology hurt a completely parallel concept? I hope the rest of this post explains this.
"In other parts of the world, politically driven Islam has overtaken Christianity and virtually abolished it."
Well actually most places where Islam is more popular than Christianity it has been so for centuries.
"Abortion, which is mostly driven by politics..."
No, it's driven by rights to choose what happens to your body, moving on.
"has devastated Christian families in many parts of the world, especially England and the northeastern United States."
No. The only way I can imagine this happening is a girls family objecting to abortion and the girl has one anyway. But in such situations it still remains the girls right to choose. Now no one is forcing you to have an abortion. That should be obvious from the positions name of "Pro-CHOICE". The idea that an abortion outside your family somehow hurts yours is parallel to a pebble dropped in the Mississippi will cause a ripple in Lake Superior.
"Same-sex marriage, which is also politically driven..."
Again, no.
"has caused ripped apart the Anglican and other Christian churches."
Ignoring your use of a verb in place of a noun which is most likely an innocent error, let's look at this. Marriage, as long as their is consent between the two adults, is a guaranteed right. So long as they don't intrude into your life you aren't be degrading by another's marriage.
"Addictions such as gambling and pornography, which are also politically driven..."
Wait. What?
"have have devastating effects on Christian churches and families." Maybe so, but no more effect than they would on another family of an equal standard regardless of religion.
"In some cases, billions of taxpayer money is used by government to erode and destroy Christian values..."
No. I think Lunalelle said it best. "Atheists don't want to outlaw Christianity. They want to make sure that Christianity doesn't outlaw everything else." No church has been attacked by the government. Not even the epitome off religious offensive groups, the Westboro Baptist Church, has been affected.
"as in some of the curriculum taught in public schools."
The only things taught in schools that is legally sanctioned is that which has the most evidence for it. If the Church is not being taught there, it's for a reason. And if you dare to teach something that goes against all evidence you are the one attacking the curriculum.
"It is entirely up to Christian churches to identify, expose and combat these indirect attacks on Christianity."
Show me one.
"In Democratic states where the government-subsidized attacks on Christianity have been most severe..."
Name one.
"Christian churches have already lost much in support by not responding to this challenge."
What challenge?
