You're right vast majority of people in Christendom are good. I've read many stories about them and their care for the less fortunate, general humanity and love for justice. Unfortunately, you can't say that about Muslims. These times were prophesied (as'salathu was'salaam) about (generalization)...in the last days, Romans will be more just than our lands.
I also think you give humanity too much credit as well. I do read Christendom papers online and their is a deliberate campaign to demonize Muslims. For example; they never identify a criminals religion except if he's a Muslim. You live in Christendom, so you know best about the mood of the people. However, if you go online forums and read comments, it seems like they just want to butcher us, even though the story has nothing to do with religion; for example the Saudi woman runner. Just read the comments about Islam in there!
A lot of people here are slightly under middle class, and you find that they are just trying to get by day by day. The wealthier and more educated ones(not just Christians, Jews and others too) do seem to have an agenda against Muslims. I myself I'm not able to 100% decipher what it is, and I and you don't need to. As per Islam, per hadith and prophecy, what's required of you now, is to abstain from the civil strifes in your part of the world, as well as the societal trends, until further notice, ie the Mahdi. So if you do genuinely believe the prophecies and advice your Prophet gave, yes there is conspiracy, but try your best to be good in character and abstain from said, until further notice.
I know lots of Muslims think of the Mahdi as someone who will give victory to 1.6 billion Muslims, my perspective, from my religious studies(independent curiosity, I'm spiritual and like reading on all religions), is that the Mahdi should not be seen that way. Because as you said, as per my studies, the Muslims are in a bad state near the last years of their nation, and there will be no 1.6 billion that will support him. On contrary, a lot will oppose him, and he is also one of biggest 'fitnah' for Muslims, in sense that he will not appear to be what people expected, and it will mean many Muslims won't have incentive or reason to declare support to this person, and thus the door of repentance closes after his emergence. So he should be seen as a trial for all people, of whether they seek salvation or not, he should not be seen in sense that he will conquer lands for some people and make them powerful and wealthy and without struggle.
As per some scholars and interpretations(ijhtihads), many are eying 2017 as the year of his emergence. If he is real .... I don't know, and I'm not into setting dates for things. But as per my religious studies, I dismiss those who say it's still decades or a century away, as per my studies, it should happen within next few years. And I read all prophecies of all religions to try connecting dots(I am spiritual). So my advice to you, the relief is not far, and try relaxing, don't worry about numbers or media, remember your Prophet and his disciples were few in number, and he said Islam will began as strange again, and he also Muslims will be great in number, but like the foam of the ocean, so Islam being strange doesn't mean everyone will be atheist or not following Islam, on contrary, there will be many declared Muslims, but religion not understood and implemented as it should be. And I'll talk about this more with you over the coming year....
