If the discussion is healthy and objective, then I think people can take the fact that they come from different corners of the world, to their advantage.. there is a real problem facing humanity on this planet today and hiding our head in the sand wouldn't do good.
Put the mind in front and the self behind and the discussion will be fruitful.
What we are witnessing is a true clash of civilizations.. some 30 or 40 years ago, nations were safe and living relatively high level of peace.. in 1980 I walked with my guest
who was leaving the country, to the gate of international departure (the bridge to the plane) at JFK Airport. I had a Yashica camera and the security guard just looked through the lens and gave it back to me. Today you can't even reach the check-in hall without a valid ticket.
The reason is that communications and transportation facilities were very limited and nations (with their cultures) were in isolated islands. Now this Berlin Wall has fallen and people are able to move around so easily.. but moving only with their bodies and leaving their minds and hearts back home.. Now the clash starts and the guy on the video above who said that they will not integrate into the society and will preserve their identity, perfectly represent this problem. If a trans-planted organ couldn't integrate with the host body then the host body will reject it.. this law applies to individuals as well.. If you can't integrate then go back home.. simply like that.
This being said, I think all major three religions are the similar, may be Christianity is a little different.. Islam is basically built on Judaism, stoning for adultery, eye for eye and tooth for tooth, position of women (with varied degree).. may the difference is that Judaism don't kill to make people Jews because you can't be a Jew unless you are born into it. Spreading Islam by force is well documented, both in the Quran and in practice, some Muslims say Jihad was used for defense but I can hardly understand someone conquers Spain (in another continent) to defend himself. But if one reads texts from other religions then he will find similar commands to deal with peoples not in their religion.. except Christianity. The Jews were the first to abrogate (practically) any reference to violence against others. Muslims yet to follow.. in the Christians case who committed atrocities against other nations, they did that in clear defiance of Jesus teachings, when Muslims did the same in accordance with their teachings.
There are Muslim schools of thought today promoting the renewal of Islam to make all laws in accordance with today's universal standards of human rights and individual freedoms, by abrogating some of the Sharia Islamic laws and invoking Quranic text that promote equality and justice to all mankind. this means reviewing school textbooks
and missionary strategies.
