Christians: why do you think believing your god is real is different than a Hindu believing Vishnu is real?

I used Hinduism and Vishnu as a randomly picked example of another religion, I could have used any other religion and the question would still be the same; what is it that makes you think believing Christian dogma is different to believing the dogma of any other religion? And please, don’t give me any of that, “If you accept Jesus into your heart...” Disney Land crap. I want clear, concise and rational answers from you because you are making a claim, that Christianity is not just another religion, and I doubt you can back up this claim, ok? So prove me wrong…
