I agree there should be no mockery etc. etc. People out there are spreading an alien religion in the name of Islam, giving Islam an unsavory reputation rather dishonouring this pure deen... Our duty is to show people that is not Islam that is being presented in the name of Islam so what do you suggest we call it when referring to it? One way, like when I used to talk to my parents was not to call their mazhab Islam but sunnism, wahabism etc. but they insisted that it was Islam. In the end I found No.2 Islam as one of the most practical options I had.
..Have any other suggestions brother Saad?
