1. In many religions, females are subordinate and controlled by men.

2. Anti-abortion and against birth control.

3. Female genital mutilation.

4. Against educating women.

The list goes on.

Religion's dismissal of science has caused as much tragedy as its use to justify war.

The idea of a “personal” relationship with a god who gives a hoot about what happens to you. I think it prevents people from seeking real solutions to real challenges.

Any comingling of religion and politics.

The most dangerous thing about religion is blind faith. Religious leaders require trust without evidence. A search for evidence is discouraged by religions, because it would cause people to stop believing, attending, and contributing money to churches. Therefore, facts and evidence are discouraged, and blind faith is encouraged. This is the root of the scam which is religion. Blind faith corrupts people's minds.

Oppression of women.

Child rape by priests

Most damaging..the belief that humans arent animals and not part of the same kingdom. That we've been "created" by an omnipotent being controlling fate.

The practice of dividing people. It's always us vs them. The saved and the unsaved, the Christians and the Muslims, the Muslims and Jews and on and on.

That you’re to take that leap of faith. In essence you’re not to question just believe. Questioning, critical thinking that’s eating the forbidden fruit.

The indoctrination of children before the age of reason to propagate the beliefs of religion, and to create a bond of belonging.

The belief in an afterlife, because it devalues the present, and helps people be manipulated into doing horrific actions.

The teaching that anyone who doesn't practice a given religion is evil.

Patriarchy.

The most damaging effect is not obvious: it is the sometimes catastrophic impairment of the pre-frontal cortex part of the brain as somebody is growing up. As a result, the ability to engage in cognitive flexibility is lost, which means that they accept as true any bullshit that their parents tell them.

In short, their parents and preachers tell them what to think rather than how to think.

That I am better than you because I love Jeebus (or, I guess,Jeebus loves me). Not what Jeebus said at all, anyway!

The teaching that--regardless of how the evidence appears--holding certain beliefs is a soul-saving virtue while holding contrary beliefs is a soul-damning sin.

The worst thing is belief without evidence.

That we don't have to give a crap about the environment, the planet, because Jesus is due back anytime.

The damage the missionaries have done.

"God created Man in His Own Image," Religious basis for separatism: Us vs All Others, end of story. God didn't Make all other species and non-living forms in 'Its" image---only Man so sayeth, who else, but Man. Next, god gave man dominion over planet Earth, to use all of its contents as man so desires (includes women, too, BTW). Oh, don't let me get started! So I'll leave it there.... 2-cents from this 1 earthling ☮🕊

In my opinion, the belief that there is only one true religion. Mostly because of all the religious wars. Plus one sort of minor thing, well not minor to me. When I was younger I started stepping away from Christianity when I was told that one of my closest friends, who believed in Hinduism, wasn’t going to heaven. If they couldn’t go, I didn’t want to go either. This person was and still is kinder and more compassionate than most Christians I know.

The thoughts and prayers mentality, without actually doing anything constructive to help.....and the tax free status of churches.

The teaching of believing myth over reality.

Complete and total submission to religious authorities under pain of perdition, and an unqualified belief their leaders are infallible in the total absence of evidence. Also, the sin fullness of skepticism and the whole renunciation of the use and authority of reason. Voltaire reflects this sentiment best: “Those that can make you believe absurdities can make you commit atrocities.”
