...(the Islam religion as far as I understand is peaceful)
the problem, in a way, is that Christianity and Islam are the only world faiths that claim to be for all the world, and therefore require their followers to evangelise others (please note that I have NOT used the term proselytise, because this has both a very specific meaning and is also hugely abused by governments and people who want to denigrate such faiths). Inevitably, there will be some tension and friction when the two meet.
Oh no doubt there is history with Islam and Christianity competing for the hearts and minds of followers - but in all of this competing the main messages seem to get forgotten, or skewed to mean something that was not intended. We need to work together and see the bigger picture for humanity - building bridges rather than brick walls.
