I will be honest a lot of people use Religions as a sort of tool to hate others while feeling good about themselves. Religions make it convenient to hate.
"Oh it's ok I will be forgiven"
If God existed and an afterlife existed, they sure as fuck are going to have a "This is your life" style book full of the many shit you did wrong. "Ain't no forgiving here buddy, down you go".
There is good people out there from all communities, who understand what it means to be a decent human being while they believe or don't believe in any religion.
Sadly the majority are hypocritical arseholes doing it for money and control. Most of this world's wars over the last 2 millennia are due to religions in the background. One of the biggest ones was Constantine in the 4th Century just steamrolling Europe and instilling Christianity every single nation he went to from Britain to Turkey, and even after his death his vision of invading Persia and overturning even Arabic Christianity happened. That's right My Christianity is better than yours, so you die.
Even today that is still evident in some nations - Protestants vs Catholics in Ireland/N Ireland with Scotland (Central Belt). That hate still exists today.
