If they want to sit in their front yard and sing Kumbayah all day long, then no one is going to bother them anyway, because they would be largely irrelevant.

i beg to differ. if someone objects to paying taxes on the grounds of the unconstitutionality of federal expenditure of funds, they get jail time. there is no such thing as an optional tax where the government sees fit to impose its will.
