And at what point does the collection of taxes levied by laws passed by fairly elected representatives of a free people, become theft?
Pretty much whenever such laws involve coercion to deprive an individual of his rightful property. The fact that a majority of citizens “fairly elect” representatives to enact laws which take property by force from its rightful owner does not give that taking moral justification.
Isn't that all taxes? What tax doesn't meet that definition?
When scripture says pay taxes, what taxes meet your non-theft criteria?
