Stephen Flynn,

"The worldview of atheism is secular humanism."

Not all atheists are secular humanists...

"In 1957, two secular humanist organizations were defined by a U.S. court as religious organizations and granted tax-exempt status."

The only time secular humanism was mentioned as a religion was in a footnote.  It was giving tax exempt status "to grant support to elements in the community regarded as good for the community,”. 

Furthermore, In 1994, the Ninth Circuit soundly denounced both the classification of secular humanism as a religion and evolution as a religious tenet. In Peloza v. Capistrano Unified School District, the Ninth Circuit held: 

". . . neither the Supreme Court, nor this circuit, has ever held that evolutionism or secular humanism are “religious” for Establishment Clause purposes. Indeed, both the dictionary definition of religion and the clear weight of the caselaw are to the contrary. The Supreme Court has held unequivocally that while the belief in a divine creator of the universe is a religious belief, the scientific theory that higher forms of life evolved from lower forms is not. [Edwards v. Aguillard (1987). Peloza, p. 521.]"

"To ask taxpaying citizens who believe in a creator to tolerate censorship of their views in a public school is unreasonable. When schools want to speculate on the origin of existence, if teachings on intelligent design and creationism are excluded, I don’t call it an education."

Schools don't teach creationism (or the renamed creationism known as "intelligent design", because they are not scientific.  They do not have evidence to support them, and are not even falsifiable - they wouldn't even hold up as a hypothesis.

"No atheist is all knowing, therefore there is much he doesn’t know."

True, I admit there is much I do not know.

"For an atheist to arbitrarily decide there is no creator might be what he wants, but is it realistic?"

I don't know or claim to know if there is a god, but I feel it would not be rational to believe in one until sufficient evidence has been presented.

"No scientist has ever produced or observed something from nothing or life from non-life"

Not yet, but I think quantum fluctuations would count as "something from nothing".

"nor disproved the laws of thermodynamics."

Nope, we haven't disproved them.

"Since there is something and there is life and it is orderly and extremely complex, to believe this all accidentally evolved from nothing is a bizarre leap of faith."

I don't think you understand evolution. 

"If an atheist conforms to the mores of society because he believes it to be in his own self-interest, it does not make him moral. The test of his morality will be when society becomes destructive of human life in whatever stage of growth or he is put in a position of power."

Okay.  So are Christians only good because they believe it is in their own self-interests because it allows them to escape hell and get into heaven?

"How will he react?"

I don't know, atheists are all different.
