"If we think what they do is so unacceptable, how come we are not offering blanket asylum visas to anyone subjected to sharia law? That I would support. "
To put it bluntly, the answer to that is politics. Countries other than Afghanistan have Sharia law (Saudi Arabia, for example). The difference is that, in the eyes of the West, SA is happy to leave other countries alone and does not seek the establishment of Sharia law in countries other than its own. The Taliban and other fundamentalist islamic organisations seek the establishment of Sharia law across the whole of the world. Central to that aim is the idea of war to spread Islamic belief.
Of course, not all Islam is concerned with this ideal and I am not trying to tar eveyone with the same brush, I'm trying to draw a line between those of the Islamic faith who see it as possible to co-exist peacfully with non-Islamic faiths and societies and those who see it as neccessary that everyone become subject to Islamic law.
Like any religion, there is a huge spectrum of beliefs across Islam and the Taliban only represent one position on that spectrum. However, they hold a disproportionate amount of influence on our foreign policy because they choose to project their beliefs outside their own borders - they'r currently involved in conflict in Pakistan and have gained control of a sizeable part of the North of that country.
"What horrified me was the 'kill or be killed'. No, it's not as simple as that. If that is our attitude and we are not the 'primitive' ones, how the fuck can we expect them to think that their survival does not depend on them attacking us? "
Our attitude of "kill or be killed" is a direct response to Taliban attitude of "follow us or die". Their belief is that in attacking us, they do God's work because we are infidels and must die or be conquered - how can we reason with that?
