Christians here are rather rude, if this is what Heaven has in store I welcome my fiery hell. Would you agree?

The actions of followers, especially when they are not actually following the teaching of the religion, is hardly a basis for judging the faith or the end goal/result. If Heaven is to exist, would you really believe that the failings of the followers here on Earth will dictate the state of this Heaven there? I would think not. Don't let those with the biggest mouths and the littlest faith (usually those go together) ruin your impression of a belief structure.
