And all this time, I thought it was to protect us from religious zealots. You know, those people who want to teach mysticism in place of science. That group whose religious leaders say God allowed 9/11 and Katrina to happen because of gays and feminists. Yea, they are creepy and dangerous. They spawned Timothy McVeigh.
A Look Back in TIME: Interview with Timothy McVeigh - TIME Time Magazine interview with McVeigh where he was specifically asked about his religious beliefs -he was raised Catholic and was not a particularly devout one. What he DOES say in this interview, even without admitting his guilt - is exactly what motivated him to do what he did. And it was not his religious beliefs.
Personally the people I find MUCH scarier than those who think God made Hurricane Katrina because of gays or whatever - are those who think the 1st Amendment was intended to place restrictions on those with religious beliefs. The religious ranters are merely offensive and can be ignored, the other ones are SPECIFICALLY out to restrict MY rights though. The Bill of Rights spells out the restrictions placed on GOVERNMENT -and ONLY government -none placed on people. The Bill of Rights lists the specific rights WE THE PEOPLE have claimed for ourselves and SPECIFICALLY forbids government from interfering with those who choose to exercise or choose to NOT exercise those rights. Until the 1960s or so, the only exceptions to forbidding government overseeing or interfering with the exercise of any right has been if the specific practice or occasion poses a real public safety issue -and that risk must be a real one, not a theoretical one.
While people like you seem to clearly understand why it is a gross violation of rights for government to order people to pray, you have to deliberately ignore the FACT it is actually no less a gross violation when government FORBIDS people to pray. One is not a worse violation than the other, yet we allow one while pretending the Constitution only forbids the other when in fact it forbid BOTH. Government was restricted from INTERFERING at all -neither ordering people to pray nor ordering them to stop, neither forcing people to participate in religious practice nor ordering them to stop. And in the Bill of Rights, not only are there no restrictions placed on people with religious beliefs and all restrictions placed on government to leave them alone - there are NO restriction as to WHERE they may practice their religious beliefs including government property.
The notion that my freedom of religion means I must keep it behind closed church doors and that my freedom of speech only meant speech addressed to another person is protected speech while government could regulate or punish me for my speech addressed to God -is FALSE. There is NO "right" to not hear certain religious speech or prayers just like there is no "right" to not hear certain kinds of political speech -and saying there should be on the grounds it might OFFEND someone is bullshit. I find a whole of liberal political speech to be incredibly offensive -but just because I may choose to be offended by it still has no bearing on the rights of liberals to express those political opinions. Feeling offended is always an individual CHOICE and people choose to feel offended by all sorts of things real and imaginary. You have the right to feel offended by whatever you want -but your FEELINGS should not EVER dictate whether I get to retain my full rights.
Liberals like to pretend that FEELINGS have "rights" - even suggesting that FEELINGS have greater rights than people do. Feelings never have rights -only people do. This pretense that FEELINGS have rights is not only the foundation of "political correctness" but was an instrumental tool for the bastardization of our Constitution in general, and specifically for the bastardization of the 1st Amendment.
