Is the reason some theists perceive Atheists as immoral?

Research shows that the reason humans struggle with emotion to find equitable solutions is pinpointed the region of the brain called the insular cortex, or insula, which is also the seat of emotional reactions.

The fact that the brain has such a robust response to unfairness shows that sensing unfairness is a basic evolved capacity.

The emotional response to unfairness pushes people from extreme inequity and drives them to be fair. This observation shows our basic impulse to be fair isn't a complicated thing that we learn.

It therefore fully illustrates that all humans have morals controlled by the brain and that Christians are entirely wrong to try and claim morals as their own!!!!

But Christians found a way round it!

Government statistics show that christians are vastly over represented in prisons for sexual, violent and fraudulent crime!

The Catholic church is paying millions in compensation for the sex/pedophile crimes of their priests alone!

Christians are vastly over represented in the divorce courts!

Christians invented the concept of sin and then the idea that you could sin, ask forgiveness, get pardoned and start with a clean sheet!

So no surprise that they are so expert at it is it?!

A Christian is a man that feels repentance on Sunday for what he did on Saturday and is going to do on Monday. - Thomas Russell Ybarra

This is more or less a straw man argument. I've never heard any intelligent theist or Christian argue that atheists can't be moral (of course, some are immoral). Rather, the real argument is that atheists don't have any good basis for any sense of morality. To use your example, if you are an atheist where do you believe inherent human rights come from? They are not inherent because of any God given rights, or because we are made in the image of God or anything like that. So what basis do you have for believing in "inherent human rights"? If you come from an atheistic view, then morality is nothing more than the relative opinion of a person or group of people (subject to change over time), or something that evolved because it provides some evolutionary advantage for survival of the human race. You have no reason to think that your opinion of "good" or "bad" is any better than the opinion of someone else, or even that there is any real meaning in talking about such things.

We're perceived as the personification of the worst things theists tell each other about us.

Not because it's true, but because it fits the anti-reality fantasy-centric narrative that they and their followers must be convinced, most of the time with the belief that faith is superior to anything non-belief is falsely associated with to "tempt believers".

Lest they question the validity of believing a false narrative propped up by mass delusional proof of hundreds if not millions of human mental constructs, all intertwined upon a similar narrative of assumed religious magic as the cure all for whatever human problem is beyond the reach of ordinary human control.

because of the fact theists define their very own standards of morality, on the exceptional of it incredibly is concept in a deity. Atheists -are- immoral by skill of a ethical common that, um, does not save on with to atheists...

Because they think we're some sort of threat

We promote science over their god, their god with which they claim to be the giver of all morality amongst many other things. So they fall back on 'Well, we draw our morality from god, and that the only place it comes from. If you don't believe in him, then you don't draw your morals from him, and as he's the only moralistic source available, then you must have no morals, making you immoral'

They've not heard of social morality it would seem. Or independent thought

So you've never told a lie, never stolen anything, never said anything about someone that was untrue, and never lusted after someone, is that correct? As believers, we know we have broken certain moral laws. Man instinctively knows that certain things are just plain wrong. We believe God put that sense of morality into us. We believe that the only thing that can purge that sin from us is the sacrifice of Messiah Jesus. Since you believe yourself to be righteous and capable of saving yourself, that your "sins" need no expunging, we perceive that you are immoral for denying your creator and living under the stain of sin. You answered your own question. We believe, and you do not.

Many theists (not only Christians) believe that Atheists are immoral because they believe that without a fear of what lies beyond death for bad behavior (or a reward beyond death for good behavior) that a person will feel as if there is not consequence for immoral actions.

It stems from the fact that some people do not seem to realize the fact that some people can be "good" even if they do not believe in God or are unsure if they do or not (agnosticism).

these people also tend to believe that you can't be morally good if you do not believe in the same way as they do.

This is from a narrow-minded viewpoint that is all too common in this day and age. That some one who lives by his or her own code of ethics can't be good unless those ethics comes from a higher power.

It's all sad and I tend to ignore what they think.

Some atheists perceive atheists as immoral, you know. I wonder if those atheists think that atheists would be better off believing in a God.

They say they appose the bible and its morals.They tell christians not to preach the gospel to them and use the courts (USA) to silence christians free speech and freedom of religion.It is their "super right" to promote and defend anything they approve and agree with.It is also their "super right" to silence,mock,and *** Whatever they appose.Since they don't believe the Ten Commandments and don't want people's immorality to be infringed.Will they approve a thief to take all they own?Will they approve adultery or fornication.Are people born with the right to lie.Are people born to be able to do whatever is right in their own eyes (except be a christian and believe the bible)?Where are moral lines drawn (by governments?)?Who decides & why?
