You keep repeating this most ridiculous statement:
“By US law, science is what scientists say it is.”
It speaks volumes about your background and intelligence.
So you say, but nevertheless, it is a fact: the US Supreme Court was asked to rule, and did, saying that religion is not science and scientists alone will determine what does, or does not, qualify under the term "science".
That's why you are not allowed to go into public schools and teach your religion in science classes.
Of course, I totally agree that you should teach your religion in religion classes of public schools; at the same time, have no problem excluding insane religions (i.e., some cult worship, or that alleged "religion of peace") from public schools.
But normal denominations, taught as such in public schools could only be good in many cases, I think.
