I would not have a problem with you doing that. I would sit there with a smirk on my face and relish in your ignorance, but would have no desire to run to my local attorney and have an injunction filed because I felt threatened by your actions. As I see it, I am firm in my beliefs and secure in what I believe, so much so that if I hear prayers from a Muslim cleric I do not feel threatened by them, no more than i would be if I walked into a Wiccan ceremony or a bunch of Devil worshippers. My point is that Mr. Green, and his lackies (of which you are since you promote his agenda) think that you have acheived some great victory over the Christians who are trying to take away your freedoms. You have done no such thing. In reality, a moment of silence is fine with me, I have a problem with your liberal ideals and the hypocrisy of a group that finds it is OK to suppress one groups public speaking because you feel threatened by them.
It is OK to say you are scared....the first step to solving your problem is admitting you have one.....lol.
Perhaps when the whole stadium breaks into a prayer, which will certainly be much louder and more heartfelt than a simple person's attempt to acknowledge God, Mr. Green can live with the fact that he probably did more for Christianity in the community than if he would have just kept his mouth shut, sat there, and smirked......lol.
