Islam is the only problem...you are what you believe in...Islam is a supremacist religion and its theology is about how Allah perfected all previous messages sent through prophets (It took Allah a real long time to get it perfected !!). Any one who doesnt agree with Islam is a Jahil or in darkness and Muslim is encouraged to use all means including terror and deceit to establish Islam....there is absolutely no way you can modify such a fascistic religion at all. Islam comes with its package jizya, chopping hands & heads, imposing veil, blasphemous laws which can kill at the slightest 'insult'. The only advise you can give practising and believing Muslims is to Leave Islam, or else society has to devise ways to grapple with this ideology. Its not Muslims, its Islam that needs to be tackled, not the other way around.
