That is not our purpose. They may or may not. Our purpose is to have free speech as others do, we are offended at any number of spoken thoughts on TV - do we get the ACLU to proclaim our rights?
Why are you so afraid of a Ten Commandments Petition? Why are you so afraid of religion - you have the choice to ignore as we have the choice to ignore that which offends us. We do so every day.
And if you wish to pay to have the decalogue placed on private grounds, 50ft high in blazing neon that is your right (zoning laws notwithstanding). However, when you are asking me to have my tax dollars go towards promotion of your religion, and put in a public place (courthouse, school etc) then it is very hard for me to ignore this, especially due to the establishment clause - would you be in favor of state/federal funded plaques with words from Allah or Buddah on them?
