How so?? Nothing in this ruling prevents anybody from practicing any religion, it just says you can't use Government power and money to make children recite a Pledge that includes an assertion that one monotheistic religion has primacy over all other belief systems. While I understand that the majority of folks here are Christian,(and I have my Nomex BVDs on) not everybody is. A single public school class may well have adherents of Islam, Buddism, Native Americans, Hindus and Athiests, as well as Christians, in it. There is no legal justification, or practical reason, to force those kids to recite The Pledge as modified in 1954. Simply dropping the two words added by Congress would still allow patriotism and respect for the Flag, and what it stands for, to be instilled in kids without offending anyone's religious sensibilities.
If the Constitution doesn't protect all of us it doesn't protect any of us.
