Could he pass out free copies of the Koran at a Christian rally?
In a PUBLIC place, that is reserved for a NON-EXCLUSIVE meeting of Christians, I fail to see how he would be prohibited from passing out anything at all. Koran, Buddhist, Wiccan or Athiest.
I need some paper to use in starting the wood stove. Pulp korans are as good as any for that purpose. But slick coated paper- not so much.
