Do you deny that there are those who oppose this? Do you deny that there are those who have brought into question publicly the constitutionality of students granted the opportunity to "observe a moment of silence?" Think about it carefully for a minute.
To go a little further on the subject of this thread, I am already on record that I am not in favor of public prayer except at church or in my home. But I will tell you this...there are still several schools in my county who have a public, "Christian" prayer before sporting events, at graduations and such. All of the schools in the area have a "gather at the pole" day where a prayer is said. All of them still have a Baccalaureate service (conducted by some sort of "Christian" preacher) at the end of the year...attendance voluntary of course but still on school property. My point is that there are still sections of the country who would fight you tooth and nail if you tried to take those things away from them in the name of "separation" of church and state. Right or wrong, that's the way a lot of folks feel. Social conservatism may be waning in a lot of areas and softening in a lot of ways, but like it or not, it is still strong within a pretty good size segment of our society...so much so that many don't care what the SC rules.
There will always be people who oppose something, but the rule allows a moment of silence and those areas of the country still stuck in the 1950's will one day come into the new century. The world is moving from darkness to light and from conservative to liberal.
