Like all those ultra-liberals on the Supreme Court?
1) They're not ACLU cases.
2) Do you have sources other than WorldNetDaily? The page I found those 3 cases on is an editorial and advertisement for a book about how there is no separation between church and state, including an article by David Barton, famous fake quote-creator.
3) I can't find any information on this Judge Kent case that isn't from WND or some blog quoting WND.
4) Raymond Raines was punished for fighting, not for saying grace.
5) I do agree with you on the Kayla Broadus case, though it seemed to have been far exaggerated. "Silenced and scolded" is a bit off. She was told to not invite her classmates over and pray loudly. She wasn't told she couldn't pray at all.
A lot of these types of cases seem to be more urban legend than factual account.
