Certainly, some atheists try to convert people. The main difference is I have never encountered an organised body of atheists who go around with the express mission to convert people... This is a significant difference.
There is really no difference whether or not they do it in a group, or individually.
The result is the same.
I'm not arguing that atheist organizations are pushier than religious organizations.
I'm saying atheists are - generally - pushier than religious people.
Have you ever heard of missionaries? I have never heard of atheist missionaries, only religious ones.
Your arguments are silly.
1. Do atheists knock on your door?
2. Are there atheist missionaries?
No, there aren't atheist missionaries and atheists don't knock on your door.
But media is dominated by "the atheistic agenda".
Mainstream cartoons (Family Guy, The Simpsons, American Dad) sell atheism to children.
So, let's flip it around.
Instead of "are there atheist missionaries", let's ask do religious people constantly mock atheism (and promote theism) in mainstream media? There is significant peer pressure (from everywhere) to conform to the atheistic perspective.
religious people tend to keep their beliefs to themselves" is very contradictory to my experience. I admit atheists are definitely more pushy than spiritual people who believe in god but don't follow a prescribed religion, but way less so than certain churches.
The atheist "church" is - perhaps - the pushiest church of them all, IMO.
And religious people do keep their beliefs to themselves (generally). The vast majority of religious people you will encounter in your life will not identify themselves (out of context) as religious... It cannot be contrary to your experience, unless you happen to have asked everyone you've ever met if they're religious.
I am pretty sure we live in the same State, almost certain we live in the same Country. I live in Melbourne, Australia.
Maybe you live in the Bible belt of Melbourne, Australia?

I don't know, man. Maybe we encounter the same people and I just don't think they're pushy?
I've been living in this neighborhood for 2 years now. There's a church one minute away.
I've never gotten a single flyer in my letterbox, or a knock on the door.
They totally keep to themselves.
The only people that go door-knocking are Mormons (and other Christian cult groups).
Baptist churches, Anglican churches - the mainstream Christian churches - keep to themselves.
The same goes for missionaries.
You're not describing the activities of religious people.
You're describing the activities of fundamentalists who belong to specific sects.
I must admit I have never had a jew try to convert me, I have had very limited contact with people of that faith for whatever reason.
If you had more contact with Judaism, you'd know they don't try to recruit people.
So, the Abrahamic religions aren't all pushy.
What about Hindus? Buddhists?
Have you had contact with them?
I was married to a woman from a Hindu family.
They are not pushy, at all.
Maybe - if you're unfamiliar with Judaism - you don't have enough experience with (non-Christian) religious types to make sweeping statements about religious people...
What percent of religious types are pushy, do you think?
Less than one percent, I'd say. (Whatever it is, it's a low number...)
Catholics may be pushier than atheists.
Mormons may be, too.
But religious people?
No. That's wrong.
(And I'll keep pushing until you agree with me, God damn it!
