I think a lot of religious people are pretty down to Earth, principled people who try to be good...

I agree with you.

Sometimes, here on this site, I see creationist Christians trolling atheists, agnostics and non-Christian deists and theists. And vice versa.
I don't see it in my daily life.

There are two or three atheists who seem to think it is their mission and purpose to try to undermine faith in any kind of god.
I think a part of their reason for doing so is that they are alarmed by the influence of Creationists and Alt Right style ultra conservatives - the radical far right. These people have given huge support to Trump, racist causes, the gun lobby, anti-abortionists, homophobics and misogynists. They believe the wife must submit to the will of the husband in all matters. They object to the teaching of science in schools. In some cases, such as the Red Barn Baptists, they will let their children die rather than see a doctor to cure measles (see Wikipedia).
Many Christians on the moderate and liberal sides of faith are also alarmed by these trends.

Sometimes these two or three SW evangelists-of-atheism fall from arguments into abuse, like calling the believer stupid and ignorant.This can be a mistake; some believers are erudite and very bright.

It's a huge mistake to abuse anyone for anything they believe. Most people are deeply identified with their their beliefs; they think "I am a Christian", not "I am not my beliefs". Thus, any attack on their belief is experienced emotionally as a direct attack on themselves. It raises adrenaline, literally exactly as if someone had threatened or assaulted them with a knife. It's a stupid way to try to persuade anyone of anything.
If someone has such a passion to try to shift another's thinking, they need to engage with the specifics, the detail.
Or even better, the atheist/agnostic should strive to actively help others at every opportunity. Demonstrate kindness, honesty and open-mindedness towards everyone. There is nothing more persuasive than living a good life that benefits others.

There are many Christians who support social justice and welfare, and actively work in those fields. They are predominantly kind, gentle, honest and decent people who walk their talk. If faith actually helps a person to live a better life and be happier, more constructive and more hopeful, there should be no reason to criticise them.

The majority of atheists have a preference for scientific evidence and logic but also have a strong value favouring freedom of thought and belief. 99.9% are not trolls.

To me religion and beliefs are two separate things.

Religion attempts to control and requires a large group of people to control others.

Beliefs really can't control because there fewer people.

So when you say "religions" getting along that's really a misnomer.

You're probably referring to beliefs in smaller numbers of people.

Agree. Most churches I've experienced are pretty good and with people like you say.
Many people love to hate religion and these folk tend to make rather ridiculous generalisations.
There are dreadful things that have happened in families, schools and other human institutions. I don't write off schools, families, churches or even all politicians as a result of the worst.

A number of years ago we had a family gathering. One of my cousins brought his boyfriend to the gathering. I couldn't help but notice the only people who spoke to my cousin and his boyfriend were the Christians. The non Christian family members all said hi and didn't ignore him but only the Christians sought him out to have a chat.

Im agnostic, not religious at all and dont like any sort of institutionalised faith.

With this said, there are a bunch of spiritually bankrupt people who keep tryna align normal religious people with extremes which simply aren't true. It's just petty trolling at this point, I know many religious people who are decent and respect others and keep their beliefs to themseleves.

Which religions? Why should older mean better? Might makes right? Which religion has the edge In choosing what is moral? Does it mean to be "down to earth" when it comes to blindly accepting magic based claims? Some sort of afterlife should be the motivation?

I appreciate the education and critical thinking skills that were taught. My beliefs are based on evidence. The adage I go by is: If it’s not science, it’s superstition.

good question

I was gonna respond to this earlier but the gist of my response was that a lot of the people that go on and on about either religious people or people of one political affiliation or the other, and make it their life's work to do so on the internet for total strangers, need to go touch some grass.

Is it religion that makes the difference?

To me, it's just a lot of white noise. Trolling is as trolling does.

The problem is that the most outspoken religious folk tend to be the most intolerant. And to someone who isn't familiar with the Christian community, it could easily appear that all religious folks are like that.
