All your organized so-called religions have one thing in common: the imperative to control mankind any way they can, mainly through fear. That is a HUGE problem, by having each one of these totally man made religions like Judaism, Islam, Christianity, Hinduism and so forth, each one teaching its adherents they are the TRUE religion and therefore people of other religions are not human but need to be brought into the fold through violence.
When ALL these religions say they are THE TRUE religion, one thing is POSITIVELY true:
THEY CAN'T ALL BE RIGHT and therefore the most reasonable path to take is to say NONE of them are THE TRUE religion.
THE TRUE religion might not even be found on Earth, it might be found on a planet in the Andromeda Galaxy where REAL god's or a real god manages the whole place with contented sycophants worshiping this god and even have an afterlife.
What WE have here on Earth is when you die, you are gone, except for the molecules that go back to the Earth to nourish new life.
People are SO afraid of death they have to have these constant man made links to a virtual god which makes them feel better about their coming demise, being filled with BS about going to Heaven or Valhalla or whatever.
So the main function of organized religions is 1) Keep their religion growing, and 2) Control humans the best way they know how, usually through fear. Inventing devils and all sorts of bogie men to torture the minds of susceptible people who fall for all that BS hook line and sinker.
The net result is continuing the infancy of mankind. We are no closer to world peace and tolerance than we were a thousand years ago and will be no closer a thousand years from now.
Just look at the strife in Africa right now, Muslims who hate women, POSITIVELY hate women getting an education and therefore on a par intellectually with men, those women get killed, kidnapped, shot in the head for daring to speak out for the education of women.
Christians are also killing people in Africa who are not their religion.
And of course we all know what is going on in Israel and Gaza these days.
The sooner we chuck the shackles of these religions the sooner mankind can become a truly empathic, tolerant and mature as a species.
As it stands now, we as a species, are not even CLOSE to being empathic, tolerant OR mature.
We fight wars over religions we ourselves made up as if they were real, then gloat over how many millions they manage to kill to support THEIR so-called true religion.
You of your religious bent would say, but look how much GOOD we do.
My answer, you don't judge a religion on what GOOD it does. You judge it on what HARM it does.
By that standard EVERY religion on Earth sucks big time.
Oh yes, I don't forget the crowd that says, 'there will ALWAYS be war and if religion was gone, they would just find other reasons to kill'.
If so, there would be THAT MUCH LESS reason to kill in the big picture.
The more the human race grows in empathy, tolerance, educating its people and so forth, the less need there will be for religion and reasons for wars of all kinds.
