Does this dismiss Christianity as impratical/invalid?

This is the fundamental belief among most if not all Christian denominations. Of course there are some minor specifications that vary but in general it goes something like this:

People who don't accept Jesus Christ as atonement for their
sin go to hell.

For those who don't know.

I'm having trouble determining what words express my question clearly but here it is:

Does the possibility(because I'm not entirely sure if it is really a logical fallacy) that it is a logical fallacy, render it invalid? If so does it render other beliefs founded upon it invalid?

The possibility that something is a logical fallacy is meaningless. You must conclude that something is probable before effectively convincing anyone of something. It's possible that I'm going to give you a million dollars tomorrow. For you to convince a reasonable person that I will, you're going to have to produce some convincing evidence.

Still unclear. Are you saying that in order to convince anyone that this belief is irrational I need to provide evidence?

Of course.

Where did you get the idea that if it's possible something is invalid then it is invalid?

Ok gotcha.
