"We can measure the damage done by the rapist and murderer but we have no way to assess the damage done by the self righteous." - Allan Watts
The narrow path is one that was set out for the individual, the spiritual path. The wide path is the path of religion where great numbers try to get to heaven down some super highway. I know plenty of Christians who take the narrow path laid out before them. It is not easy. It requires real faith, not some belief system. People from just about every religion do the same. It is not about belief. Belief is just a vehicle, a personal vehicle, to get you home. Judge not means exactly that. Another person's path is none of your business. It has nothing to do with you.
As I have said before, there is something fundamentally wrong with fundamentalism (and fundamentalists). A person who needs to attempt to convert others to their way of thinking is not secure in their own beliefs because they require others to validate them. There is no strength in number, your faith stands on its own merits or it falls. Like anything else, you fall, you get back up and try again. That is what life is about, trial and error. The only person that is going to judge you is you. God/Creator/Allah does not care how you get home, as long as you eventually do. There is not just one path, there is just one path for each person.
People who are as fanatic as you, Alley, are the type of people who eventually get disgusted with their fellow man because they can never live up to your expectations of yourself and eventually strap on some explosives to send all them failures to hell. I got news for you, their is no heaven and there is no hell, just what you make of this life. You will know you are on the right path if it makes you feel good, and if it feels bad (like having people mock you for your self righteous bigotry) then you are on the wrong path. How other people relate to their creator is none of your business. Your only concern, when it comes to spiritual matters, is your own "salvation". You don't get any brownie points for annoying others with your beliefs.
