God bless you Silyosha
Admittedly I was also surprised by the vicious tone of some posters. It seems to stem from paranoia of the ‘they,’ a poorly defined boogeyman. I see the same kind of mentality from the few terrorist sympathisers I’ve met. I try and cut their deluded conspiratorial mindeset by pointing out that even if the Free Masons (they of often are the they???) were wanting to deliberately bring down Islam, we don’t care because God will take care of them; we should be more concerned with how we’ll fair on the day of judgment (nice signature btw). This irrational fear just shows a lack of faith. So the irony is, is that those paranoid of terrorism are actually of the same mindset as the terrorists!
A good and welcome question

although perhaps quite a difficult one to answer. I am a Muslim from the UK that generally frequents University educated circles, thus I’ll have a certain skew that may not be wholly representative.
From my perspective and my close circles of friends then yes we feel Pope Benedict XVI is doing great work for inter-faith. One of my teachers (T J Winter also known as Abdul Hakim Murad) from Cambridge University is at the forefront of the Common Word dialogue and speaks of good relations with the Pontiff. He has given many lectures on how more Orthodox faiths have similar World views and thus should join forces against this post modernist world to re-establish God as the centre of our affairs - rather like, the then Cardinal Ratzinger, articulates in the excellent lecture ‘Europe’s Crisis of Culture:’ ‘veluti si Deus daretur.’ I would say that is how the more ‘middle class’ UK Muslim would view the current Pope.
The masses are of cause a different matter. I do not think the outrageous UK media representation of Pope Benedict as being a pedophilic, homophobic, AIDS speading ex-Nazi helps (sorry, but their words). The Regensburg Lecture did not help his PR either, not because of the actual lecture per se (not everyone actually bothers to read these things, I thought it was good) but because the media tried to present it as an Islamophobic agenda. Because of the above, many have a not so good opinion, since that is all they ‘know.’ Generally his predecessor, Pope John Paul II, was viewed in a better light by Muslims.
I also think that, sad as it is, a significant portion of Muslims don’t care. During Islam’s ‘Golden Age,’ the mentality towards Christianity and Judaism was that it would wither out of existence; they had their time, but now the new faith will supersede them. Perhaps this mentality has continued? It is an arrogant assumption and perhaps our current abasement is a lesson from God.
All of that said, the default position in Islam and thus most Muslims is one of good relations with Christians:
“…and nearest among them in love to the believers will you find those who say, ‘We are Christians,’ because amongst these are men devoted to learning and men who have renounced the world, and they are not arrogant” (5:82)."
Those that are intelligent enough to possess discernment also realise that not all Christian denominations are the same (which is of course what the verse is referring to) and Catholicism, Orthodox and High Church Anglicanism are the groups nearest in love.
Hope that helps, God bless
