If that is something you wish to focus on, you may. That is not what these religious people are concentrating on.

I doubt it. Some of them probably don't believe it in the first place, and it appears that others there have different things on their mind. But who am I to say what is or isn't on their mind. Just guessing by their actions, it doesn't seem to be a real concern.
In Islam, Jews and Christians are also people of the book. Islam is the only other religion in the world that believes in Jesus' divine message and the virgin mary. In Islam, these people are also followers and are to be respected and revered. Its ironic how individuals have twisted this message of love to the violence it is today. I watched the movie kingdom of heaven again a few days back and we see that the same problems today have been going on since the dawn of time. The religious zealots judgement of others and utter lack of humility is just astounding.
