“Is atheism against the law?”
What law would that be?
“Atheism is a lack of belief mentality which rejects the existence of anything supernatural.”
No, that’s naturalism. Science is naturalistic, so it is neutral to anything supernatural. Atheism is just not believing in gods.
“By default, atheists are also naturalists and evolutionists.”
No, it’s not automatic.
I have seen atheists that are dumb enough to parrot creationist arguments if not their conclusions (“How do you know? Were you THERE?!”)
“They believe there is a natural explanation for all circumstances and nothing has ever occurred that has a supernatural answer.”
I dunno about that. We DO recognize that the evidence requirement for a supernatural claim would be rather vast.
“While atheism does not break any state or federal laws, it does break several scientific laws.”
Nope, not a one.
Science is already naturalistic, as mentioned above.
You just think that there are things that science can’t explain, therefore god.
