Why do all of the christians on here keep generalising about atheists?

That is something of a generalisation!

Did I miss anything?

Creed

No God, anti-God, Pro-homosexuality, anti-Christianity.

Atheism is a belief. I know that many atheists will disagree with this, but the atheists gathered around a common belief of no God, or lack of God, and the need to increase what they perceive as separation of church and state in America.

Crisis

Created a problem and offered a solution. The problem was religious oppression in society with atheistic ideals as the solution.

Assemblies

Gathered in groups with meeting times. Atheists don't meet nearly as frequently as Christians do in their churches, but they do have state meetings, national meetings, and regular gatherings.

Pulpit

The lectern from which speeches were made, their ideas were promoted, and their reasons for their belief system were validated.

Evangelistic

The atheists sought converts to their cause. They frequently spoke about getting the idea of atheism out into society, and to move people away from theism.

Celebration over converts

Rejoiced when converts to their belief system were announced. There was applause and excitement when there were announcements about people who had "come out of the closet" and announced their atheism.

Zealous for their cause

They wanted their cause and belief system expanded to the extent of changing America to reflect their thinking.

Exclusive

Only they have the truth. The atheists repeatedly spoke of how atheism was the truth, and that theists and deists were ignorant of facts and reason.

Us against them mentality

There was a profound description of the division between atheism and theism, with the atheists being the ones who were defending themselves against the intrusive theists.

Concerned about public image

This is normal. They were very concerned with how they were perceived and wanted to change their negative reputation.

Lack of critical thinking

This is common everywhere. Though they thought they were rational, by far most of the arguments and comments weren't.

Misrepresentation of opposing views

Again, another common trait among people who gather in groups, have a common ideology, and see others as being less enlightened.

Voting block

The atheists mentioned voting as a group in order to progress their cause in society.

Infighting

This is normal for groups. We don't all see eye to eye. But, they all held to atheism even though they had disagreements about some particulars.

Money

They didn't have tithing, but there were plenty of things for sale. And, let's not forget to mention how they sought donations to help cover the costs of promoting atheism, paying speakers, renting facilities, etc.

Ironic how you just generalized all christians.

Thats what atheists do to us. They call us all crusaders, war mongers, etc.

You do realize that you just made a generalization, right?

Have you been here long? seems many do this to both sides here.

bless you.

Ha!

I see what you did here.

Good one.
