Why fighting about religion is just plain stupid?

Think of 2 people, both named John Doe. One of them says, "My name is John Doe." The other one says, "मेरा नाम जॉन डो है|"
Now the first one says, the only right way to say it is mine, "My name is John Doe." The other one insists that his way is the right way, "मेरा नाम जॉन डो है|"
Actually from an independent perspective, both of them are correct.

That is all that the fighting about religion/community is.

Everyone is trying to say that their religions shows the "only" correct way, but they are actually the same thing, just in different language or script or methodology or just a different path. Every religion teaches compassion, be helpful to others, don't be selfish, live an honest life etc. basic things that will help you lead a better life, whether you believe in any religion or you are an atheist. No religion (religious "god", whether Prophet, Mahaveer, Buddha, Christ, Guru Nanak or whoever it is that you believe in) ever said that fight with them because they do not follow me.

The methods maybe different, but the goal is the same, to live a happy & peaceful life & help others do that.

Look at it this way : You want to reach Jaipur from New York, now there are many ways to reach Jaipur from New York. Now there are many routes & flights that will take you from New York to Jaipur.

• Air India flight from NYC -> Mumbai -> Jaipur
• Etihad flight from NYC -> Abu Dhabi -> Jaipur
• Jet Airways flight from NYC -> Brussels -> Mumbai -> Jaipur
• Etihad flight from NYC -> Duesseldorf -> Abu Dhabi -> Jaipur 

All of these flights (& many more) will take you to Jaipur from NYC no matter which flight or route you have boarded. There is no point in fighting over which flight/route is the best, the only best route is the one that you feel the most comfortable with.

That is just how religions work, all of them teach you humanity, no matter who said it or what that religion or its followers are called.
