In the western world. What we are seeing is a massive decline in the social and spiritual order that once defined the way of life in Europe and North America. Fortress states like Ireland is now holding referendums on legalizing same-sex marriage which leaves just isolated conclaves of Christian worshippers in a society now dominated by left-wing ideologies of cultural marxism, radical feminism, gay rights, atheism and progressive socialism/liberalism. 

As I have posited in other threads, this is the direct result of Hitler losing the war. Though, fascism as a universal concept is still alive in muslim countries where it will continue to grow in oppositional defiance of Western atheism/socialism. What we are seeing in Europe is an unprecedent wave of muslim immigration especially as the Syrian war continues with no end in sight. These groups are shuffled into societies just to be abandoned by the system. These people live in gettos, have no jobs, and continue to associate closely with members of their own ethnicity/religion. 

These people become displaced and segregated and as a result they become even more polarized. Poor economic conditions will breed religious extremists who will call for universal Shariah law as the answer to Western decadence. My hypothesis is that there will be a final showdown between the left-wing ideologies and religious fascism, more so than the strife we see today which is just isolated incidents of islamic terrorism in EU and NA. 

Remember, the third anti-christ has yet to reveal himself. Nostradamus calls him Mabus. Other mystic sources claim he will hail from Pakistan or an area in proximity of that part of the world. To me this sounds like there will be a muslic cleric who can unite the islamic world like Saladin in the era of the crusades. 

It may sound as if I am a pro-western islamophobe but I'm not. I created a thread not too long ago where I said I was contemplating converting to Islam because I felt Christianity was moribound. I am, however in direct opposition of left-wing ideology and atheism as an anti-religion.

What do you think? Is Christianity "officially" dead in the West? What will happen with all the muslim immigrants in Europe? Will they integrate into society and become feminists and support abortions and gay rights?

Christianity is falling because people have increased access to information, and it is easier for them to educate themselves.
Education leads to thinking, and thinking leads to a realization that Santa Claus, Tooth Fairy and Jesus Christ are fictional characters existing only in fairytales.

It is that simple, and nothing complex and xenophobic as you make it out to be.

war..... has changed...

Yeah, it's such a shame Hitler lost, clearly the world would have been so much better off if Nazi Germany had achieved global domination...

Pretty much this.

That part really caught me off guard.

And that's saying a lot, because the whole OP basically did that.

*glances at your average person, yeah people are really educated /s* 

No need for /s

Religious people still greatly outnumber the non-religious...
