Most of the people on the forums are from the US or other Western countries where Christianity is the the dominant religion. That also means that it's the religion that most people know about when criticising.

This :D 

btw for the record I'm a Buddhist

It is because Christianity is the most practiced, most powerful, most financially supported religion in the world. With the dominance of Western society, it is probably the most widely-known religion (as in, people know the most about it). Furthermore, most people on the forums here are from Western countries, where Christianity has historically predominated, has served as the base of much of modern philosophy, and so is prevalent in modern day Western thought. Finally, most other religions are not exclusive in the same way as Christianity. For example, in Islam, what is unforgivable is Shirk - the associating of partners with God (I.E., an active sin), whereas what is unforgivable for the Christian is Blaspheming the Holy Spirit, which is interpreted as an active sin by Christians ('an active resistance to the Holy Spirit') but in all seriousness includes such things as not affirming Christian doctrine as true (I.E. not knowing). Because of the exclusive nature of Christianity, which requires its adherents to conform to a certain specified set of thoughts and to affirm them as true (whilst simultaneously denying the validity of any contradicting ideas) many people no doubt feel the need to examine Christianity while not feeling the same way about other religions.

All of these, and more unstated, are reasons why Christianity is more commonly discussed on these forums (and elsewhere) than other religions.

A few question, what, if anything, happens when you die according to your religion? Is there a Heaven or a Hell? Where did it all begin, life, the universe, etc. What do you say about Big Bang?

LOL

OT: Christianity is the most popular religion.

Love God and Love your fellow man - there's really nothing more to Christianity. So are you saying that this differs from other religions?

Are there really a good percentage of other faiths in the Western world where most internet forums are based?

Let's just look at the two most well represented countries for our site specifically. According to census the USA identifies itself at 73% christian, while the UK is lower at 59.3%. That's the answer right there, because it's the most dominant form of religion in the Western World. I'm sure I'd be happy to debate with a buddhist about religion if I ever met one who wanted to do so, but I never have.

cause people don't think to speak of other religions when it come to religion, and Christianity is still the most recognized form of religion.

and i haven't joined in on the religious discussions.

i like to refure to Greek, Roman, and Egyptian faiths. Roman/Greek  religions are not as much myth as you've been told.

sorry tried that, didn't have anything on Big Bang. So?
