What essential rights did the colonists fear that the British were violating and how exactly were they violated

In short, it is the greatest absurdity to suppose it in the power of one, or any number of men, at the entering into society, to renounce their essential natural rights, or the means of preserving those rights; when the grand end of civil government, from the very nature of its institution, is for the support, protection, and defence of those very rights; the principal of which, as is before observed, are Life, Liberty, and Property. If men, through fear, fraud, or mistake, should in terms renounce or give up any essential natural right, the eternal law of reason and the grand end of society would absolutely vacate such renunciation. The right to freedom being the gift of God Almighty, it is not in the power of man to alienate this gift and voluntarily become a slave.
