You must look at the totality in order to appreciate what America has done for all humanity. Would England still exist? Would Cuba still be a Spanish colony subjected to inhuman Catholic tortures?
You really need to get past the idea of american exceptionalism. While America has done some good in the world that good is far outweighed by the reprehensible acts commited by America of the years. My Lai, The Trail of Tears, blankets infected with smallpox, the massacres in the Phillipenes, in Iraq? What of those attrocities? Should we just pretend as if they never happened?
As for your points. Yes, England would likely still exist, By the time the US entered WWII the germans had already abbandoned they're plans of an invasion of Britain and were restricting their attacks to aerial bombing and disrupting the flow of goods to and from England, and by the time the US made a land invasion of Europe the Soviet Union had already broken the german siege and were on the long march to Berlin, german defeat was already inevitable.
And Cuba? Cuba was already in revolt when the US got involved, and the cuban revolution would likely have defeated the spanish sooner or later. After the spanish defeat the US screwed the cubans over by occupying Cuba contrary to what they had promised. The US then went about installing a dictator that was every bit a brutal as the spanish colonial government was. We did the Cubans no favors that day and they did not forget it.
But America is losing itself, and thus, by extension, losing the entirety of humanity.
How so? Humanity does not revolve around America anymore than it did around Rome. Empires fall but civilization goes on. Your problem is that you think the american people should all kiss your religions ass and that America should be about the business of converting or killing the rest of the world.
Our Constitution includes a paeon to our Almighty. Our President swore to uphold the Constitution so help him, God..
No, it does not. Try reading the damn thing first. The phrase "So help me god" is not to be found anywhere in the constitution, nor has "under god" been in the pledge, or "in god we trust on the money or as the motto but since the Red Scare in the mid 50's. You are engaging in revisionist history to prop up your "christian nation" myth.
Now we, as a nation, have begun to turn away from God, the Everlasting, the Almighty, the Eternal, the Loving
We turned away from "god" the moment our founders forged a secular nation with a secular constitution, as was their intent. They were students of the Enlightenment, with all that entails. They specifically voted down any reference to yours "god", or anyone elses during the constitutional convention.
By granting rights to those who willingly engage in perversity, we risk losing our blessed covenant with the Lord.
We shouldn't even be granting rights. The foundation of this country is that human rights are inherent, not something to be granted or taken away. Anything less is, by it's very nature, unamerican. You know nothing of the ideals that this country is founded upon, you would pervert it's ideals for the sake of your religion, areligion that you would force upon the people at the point of a sword, or the barrel of a gun. You know nothing of freedom.
we risk losing our blessed covenant with the Lord
Your "covenant" with your "god" is your own matter, it is not the concern of the US as it has no part in your covenant, nor does it has one of it's own with your "god".
By all that is right, those who practise such pervisities should not even be allowed to live.
So you would take the lives of the citizens that this country was formed to protect? What seperates your ideal america from a tyrannical state governed by Sharia law? You would take both life and freedom from people for no reason save that they don't strictly to your religious code. So tell me, what seperates that from Sharia?
God ordained that marriage is between man and woman, or, in some cultures, women
What your "god" has or has not ordained has no effect on the laws of the US. This is not a chrisrian theocracy.
No culture allows man to marry man, nor woman to marry woman. No society condones such perversity. Or, at least, no society has until now.
There are numerous countries now and throughout history that have allowed same sex marriage. Do your research next time.
Massachussets allows perverts to marry. California tries, through judicial activism, to force through the same. And now, we face a financial and economic disaster to rival the Great Depression. And it is not just America. We bring down the world with us.
A financial crisis that was looming and inevitible long before gay marriage was allowed in any state. It's origins lie with irresponsible fiscal policy, not with your imaginary friend. Quit trying to scare people into your religion.
In the 1920s, America turned away from God
How so? I'm willing to bet you don't even have the slightest idea what went on during the 1920's.
We were punished with depression and war, both of which reawakened American religiousity. Today, we have war and a burgeoning depression. Our only hope for America, nay, for the world, is to embrace God in all His infinite reason and infinite love so that the world may be born again through the cleansing of disaster
So your "god" of "infinite love" feels that humanity must be put through a "cleansing disaster" that will no doubt take hundreds of thousands of lives, just to prove that he loves us, and that he's willing to kill us to make us love him.
Better one woman be denied a visit to her partner than America be damned. Better two men are kept out of pervisity than the world be lost.
No, better that religion die a long overdue death than for a single person have their freedom taken in it's name.
