I have a better idea, Luke! Vote with your dollar! Don't go to McDonald's or the other places that sell meat. The activities you suggested will only land you in jail.As for the First Amendment, don't go there! The Constitution does not give you the right to tresspass on privately-owned property and make an ass of yourself.
If you don't intend to buy food, then you have no business on the premises...period. If you choose to be a vegaterian, that's your decision. I choose to eat both. I'm not going to get in anybody's face and push my choice on them.
To close this, back off, and let us enjoy our occasional Big Macs and Quarter Pounders...bought with money we worked hard for...in peace.
Much love,
Mike.
