GOTCHA!
No one said anything about "one faith" but you!. The original article mentions Judeo-Christian faiths being represented, so the suggestion that only one faith is being represented is a fiction.
It also means that the First Amendment doesn't apply since the government is not establishing any single faith as the state religion.
That doesn't really matter. The government is still treating certain faiths differently from others. The fact that there is a group of privileged faiths, rather than just one, doesn't make a difference.
"GOTCHA!"?
You denied that they weren't discriminating against her faith. I have proven that they were, by their own admission.
Gotcha, yourself.
The board is promoting some faiths while specifically denying others.
Does the addition of the word "some" make you feel better? Does it make their actions any less un-Constitutional?
