Read what you can about the Caucausus and its people. They have been living in that location, with their own languages, culture and traditions, for thousands of years. Islam is a recent addition, something that was adopted to give them strategic allies in their fight against Russian incursion.
Among the many sites you could visit to learn more about Chechnya in particular, its history and people, is this one run by the Russian government: www.chechnyafree.ru. There are plenty of others with strong points of view on the human rights and political situation. Google is very helpful.
If you'd like a link to some recent pop music, Chechen and Russian, with no hint of political content, here it is: http://www.chechnyafree.ru/index.php?section=Vidrus&lng=eng
There is plenty more interesting music and video on this site.
Islam = Animals all I need to know.
