Lootoo, here is the abridged version.
You're using semantics. But that's okay. I can too.
Atheism = lack of belief of the existence of a god
Theism = belief of at least one god
Neither of these terms possess designs over belief systems. They are base matters of fact.
You say Stalin didn't kill religious people in the name of atheism. You could go further and say Stalin actually committed those atrocities in the name of his belief system - namely, Communism. Marx himself said that Communism is at its root atheism but not vice versa. This is important.
The same is true therefore the other way round. Atrocities aren't committed in the name of theism. They are committed in the name of a particular belief system. For example, the Inquisitions. People were tortured and killed not in the name of theism itself, but in the name of the Roman or Spanish church.
We're splitting hairs but what I'm trying to say is that both rules must apply. So for you to suggest that one way is mass human atrocities and the other way is removal of crucifixes is just absurd.
Next - As I mentioned before, in the context of having to discuss this, an ignorant atheist zealot is much more painful to endure than an ignorant religious zealot. Apply my assessment above and you ought to discern the differences.
Finally, you certainly did allude in your post to me being a lapdog of someone in particular. Be brave. Who did you mean? If you say Bryant, I'll get my coat :-D
