atheism is a cause brought on by the oppression of inferior religion. I would say not all religion is oppressive, and unjust. but Christianity and Islam demand conformity.
scientific materialism is oppressing people as well to conform to their beliefs.
seeing that people are individuals, we should all respect people's rights to be convicted of whatever faith they choose so long as they don't oppress people with the conviction.
people should be free to express their convictions so long as they aren't delusional judgments on people's souls.
there is a need to contest religion, because it is an enemy to freedom of rights. religion should be subject to lawful interrogation, and prohibitive restrictions. or perhaps we should all fight it out under the protection of free speech. it's just that religion is accusatory of those who don't comply.
religion should be better than what we currently have, and it isn't.
I subscribe to free will and the right to choose one's own self so long as it is harmless to the general welfare.
unfortunately many, many millions of people are religious in the accusatory way.
