Terminator, first they try to befool by qouting some verses / instances which have been written for muslims in quran and which talk about harmony. But when verses which spread hate and violence agaist non believers are brought to their notice then they term them OUT of CONTEXT. But if you still prove conclusivly that Islam is intolerant and uncivilised religion then they resort to this type of activity.
I agree there are bad practices in every religion but follower of that religion shud be open to the discussion and shud be ready to condemn those practices
