Islam works by stripping people of their hope.
Again this is very true too!
They also prey on hopeless people. They spot someone with weak faith and unleash their little quranic lies and give them "hope".
Othertimes they will take someone's hope away, like you mentioned.
They point is, that they like to talk to those who are ignorant, don't know any better or who are "hopeless"
unfortunately most religious outreach people target people without hope, and they tell them the world is pointless and worthless, and all the matters is religion, and work is a necessary thing you have to do to support yourself. fair enough!
The big problem is that in islam, the hope is to politically take over. That is all that is worthwhile for them.
Other religions are fairly harmless.
For christians I suppose hope is hope of going to heaven, acheived through believing in jesus. And acting as he did I have seen the WWJD "what would jesus do" bracelets!
And although religious jews do not really play the hope game.. There is hope of moshiach coming, though that is inevitable.. There is hope of bringing it nearer.. We have mitzvot, which free ourselves from the mundane, they are G-d`s will, and thus worthwhile. (working is also G-d`s will though. he said 6 days you should work and on the 7th , you shall rest). But the real hope, from a kahanist perspective, is the mitzva of Kiddush HaShem, for example, making israel a jewish state.. And trying to remove Chillul HaShem, the desecration of G-d`s name that is occurring.
