I mostly agree with Jonas and Johan's points.
If only religion could be removed from the equation I would have very few issues with immigrants... But as soon as they bring the negative and disgusting aspects across a border and expect other countries laws to bow to their backwards "values" and spiritual laws I start getting really pissed off. European countries did not work hard to gain peace through a more secular society just to have some religious nutjobs disrupt shit like the middle-east.
My true prejudice is Religion, and frankly I think it's a good prejudice to have. No religion should be accepted or tolerated as harmless beliefs, because that kind of ignorance towards reality and facts is dangerous. This whole world would be a lot better off if it were gone...
So with that said, anybody else in favour of making contact with Aliens??
I don't even care if they're hostile, that kind of event will completely uproot and fuck with people's archaic beliefs. Even crazy ass fanatics wouldn't know what to fight about once they have literally no way to back up their ideology. I'm sure some of the really crazy ones that obviously already have a mental illness will still do mental jumping jacks and find some excuse to keep being horrible people. Still, if something world bending like a new alien species comes along they are forced to confront an entirely new reality and even if they don't like it everything we know still comes into question. Moderates on the fence are suddenly back to the real world...
....And if that doesn't work they can send the Xenomorphs to fix us.
