I am sure this has happened but it is not the case for most Muslims. I know Jews (not bashing, I am proIsrael) who have disowned family members for converting. Radical mormon sects have "divine atonement" where they kill people to save them. Usually this is for leaving their belief system. You can't say that Mormons are blood thirsty for a few. It is the radicals that get most publicity. How many new stations want to broadcast: Christian church gives to the homeless, Muslim or Jewish family living a peaceful life. No, people want to hear Christian pastor preaches hate for gays or Muslim terrorist blows himself up in a mall. This sells more newspapers.
