The solution is simple:

Do away with organized religion.

We are not as ignorant in science or life as we once were. Religion has no place in government anyways.
If you hold a belief, then keep it to yourself. No more gatherings... No more churches .... No more collective violence.

All religion requires faith ...so then why continue, as a world population, to tolerate violence in the name of something that no one can prove exists? Its ridiculous.

The world needs to wake up and stop drawing lines between people based on imagination.

Follow the old testament... Dont follow the old testament. Who can prove it was truly inspired by god? No one!

Besides... No one follows it to the letter. If it was inspired by god...who un-inspired the parts we dont follow? Again ...it's ridiculous.

Humanity has sacrificed a lot on behalf of religion ...isn't it about time religion sacrifices for humanity?

I'm not saying do away with religion itself ... just reduce it to an individual.

NO MORE ORGANIZED RELIGION!!

The only real answer to stop the violence.
