"For evil to flourish, all that is needed is for good people to do nothing." - Edmund Burke
I hardly know where to start.
The First Amendment to the US Constitution guarantees freedom of religion.
The senders of the e-mail obviously disagree with that amendment, or at least the part that refers to religion. I wonder whether they think the other parts, freedom of speech, of the press, of assembly, are wrong too. My guess is that it's just the religious freedom bit they don't like. Or at least, if it applies to any religion other than their own particular branch of Christianity.
(I wonder where they stand on the Second Amendment too...)
Scary! Isn't it? What's scary? People saying their prayers scares you?
"A Christian nation cannot put up a Christmas scene of the baby Jesus..." Who are they blaming? I've never heard people from other religions demanding such things.
There are examples of this kind of stupidity but it comes from 'Christian' councils, officials, individuals, usually on the ridiculous basis of 'we don't want to offend anyone' - forgetting that they are offending Christians.
...this is not in France, Middle East or Yemen or Kenya (you've spotted the Obama reference there of course, and the old France-bashing dig). It is indeed in New York City. But NYC is in the USA, which guarantees freedom of religion. So the problem is...?
"For evil to flourish etc". Evil? What evil is being shown?
The photo shows pious people, too many to fit into their place of worship, peacefully and legally observing their religious devotions.
No prizes for working out the agenda of the senders of these e-mails.
Thanks to jadaoun for pointing out in his comment the Snopes page on this subject.
In fact the whole thing is based on a lie. It's a complete misrepresentation.
The photographs are of an annual event, like the St Patrick's Day Parade and others.
