I'm a Muslim and can tell you it's wrong. #1 mistake most people make when they find contradictory facts in the religion is not taking the context of the verses or quotes they are examining. Arabic is a very rich language and a direct translation in most cases does not yield the full meaning. We believe in Jesus' _original_ teachings as much as the other prophets. I think the onus is on you to demonstrate why you think that. Also remember that the actions of a terrorists that claim to be Muslim does not reflect the actual substance of the religion.
That's a pretty poor defense in this day and age. Countless books have been written on the topic and I have read many myself, youtube search will easily bring countless imams explaining the death penalty for apostasy and what the hadiths say about how to treat infidels.
so you can't go pretending those things are not there. If you feel embarrassed by barbaric desert god who behaves like 8th century human, then perhaps proper reaction is apostasy and not defense of the bronze age mythology.
