Having said that Islam is an ideology not a religion that wants to rule the world.
Yes, the reformation needs to separate the two and make it into a religion only, not pseudo-religious-facism with political aims.
Each country must protect its freedom, identity and democracy. Resistence against Islamization is a patriotic duty. The National Flag above the bible/ koran.
I think freedom and human rights are the most important things. Identity and democracy are just mechanisms that typically help achieve those.
It's that possible? The future will tell.
We can only hope.
My fear is that current islam extremism is not going to disappear without a 'jolt' to shock people into change. Japan was transformed from a rather cruel, brutal culture into a very peaceful one today but it took atom bombs and a world war. Germany changed but again, it took dreadful measures (firebombing). Other cultures have had more relatively peaceful revolutions and changed (e.g. communist russia, east germany). Even closer to home, the US and UK used to take part in slavery and all kinds of abhorant practices.
So yes, it's definitely possible. What we need is to promote good ideas and destroy the bad ones.
Sadly, it seems we can't even be critical of bad ideas yet as they are enshrined within islam and too many treat it as unquestionable.
