Research on altruism shows lower levels of altruism in children with religious parents. Does that help?

Religion, belief or ethnicity doesn't prove kindness
It's your personality

I doubt a difference in which is kinder. I do believe that an atheist tends to think out the consequences of any acts of kindness before acting on them more than a believer does.

my experience is that kind people are kind, unkind people are unkind, most people are kind most of the time, and their religion or lack thereof is irrelevant.

If everyone treated everyone like they wanted to be treated, I think the world would be a better place.

Depends on the atheist and the believer.

I've known kind empathetic believers as well as hateful ones.

I've known kind empathetic atheists/agnostics and I've known hateful ones.

I think it depends on the person.

Religion obviously doesn’t give one any advantage in empathy despite them claiming a monopoly on the virtue.

I was raised Hindu and was taught that giving is a gift. Xtianity teaches give and thou shalt receive.

However the community I was raised in, showed kindness to everyone regardless of what faith they followed.

After leaving home and living in another city - most of the believers I know, give with an agenda. Most of the Atheists i know give selflessly and are involved in charity, human rights etc

...but I also agree with what @ScienceBill72 says.

Kindness - meh - But in thoughtfulness and true and genuine help, my experience has been more positive with non-believers, and open-minded believers. I prefer to be surrounded by people who are doing the right thing by people and doing it because that's what's in their heart for altruistic purposes, not to get brownie points for getting into some gated community in the sky.

Religion or lack thereof does not dictate one's morality, thus whether or not they believe is probably irrelevant as it relates to how kind they are.

I think whether an atheist is kinder than a believer depends on the person...not the beliefs. Now if you want to talk about being judgemental then I would say, in my experience, that an atheist is less judgemental.

Have to agree with the previous posters . It depends on the person , not on their religious beliefs .

Its hard for me to say, the places I worked, esp now in entertainment, we don't talk about beliefs too much. I would say the few I know who are believers do tend to be nice and pleasant to work with. Only one person years ago, seemed out of place to be in entertainment, where we are open and really can talk about anything. This person was why on the more reserved side . I would also imagine some others, who may fall under non denominational , might be nice, but could be a bit arrogant, or condescending, even though they are nice. The few athiests I know at work are good, smart, have a side of them that don't take stupid people/arguments lightly.

In my experiences, in a word, yes. No doubt about it.

I think this question presents us with a false cause fallacy.

Nah. I've been fortunate to experience kindness from many regardless of spiritual background or lack thereof. I think that the bait of some eternal reward taints the purity of the intent but the result is unsullied.

Well we don't do things for people just to convince them to convert lol

I think it really depends on their personality and Character, it depends really on who raised them and influenced them in their early Life, and where their heads At. Race and background don't matter either, some poor people are as big an Asshole as rich people can be , same with being Nice or Kind

In my experience, there is much hypocrisy among believers (christian mainly), and hypocrisy is never kind.

No I don't think atheists are kinder. There are nice atheists and some atheists are assholes (I've met and dated a few on here!), just like some people of faith are kind and some are total fucking asshole douchebag pussy-grabbing tax evading draft dodging scumbags. Vote!

I don’t believe so. I have met some very rude atheist and very kind believers in my lifetime.

For myself I'm in total agreement with genessa. But then again most of the posts are along the same lines. Be kind, be cool and be well.

we all have our beliefs that we at some moment in life accepted at face value.
It would be highly impractical to ask for evidence of everything in life.

Since I don't ask if people I meet are atheist or among the faithful, I don't know.
