Re: the vast majority of terrorist incidents world wide are linked to Islam
How many western countries currently have the death penalty for apostasy or homosexuality or adultery?
Unless those countries you are thinking of are specifically theocracies, they will have a separation of state and religion, and thus their laws are a cultural, not a religious artefact. Don't conflate what are societal norms in a culture with religion. Very few countries have the death penalty for apostasy (although there is no excuse for those that do), and several sub-saharan african countries that are nominally Christian have the death penalty for homosexuality or adultery.
The fact is that Islam encompasses a vast number of people from different cultural backgrounds, and you are insinuating that they all behave like the lowest common denominator. It's the exact same faulty thinking that equates all Christians with racist bible-belt gun nuts.
