How to ensure a religion spreads like wildfire

Which is what Islam is doing. 1. Forcibly convert everyone in countries that you take over. 2. Subject all people to the same law as those who are that religion 3. Kill anyone who tries to convert to a different religion 4. Kill anyone who mocks your religion 5. Kill anyone of the same nationality as the person who mocks your religion, regardless of whether that individual mocked your religion 6. Whine about prejudice if folks in countries in which people of your religion have immigrated, do not bend over backward to provide you with the tolerance that is never extended to people of other religions in your own country.
