Answer:
That all males are created equal.
Step-by-step explanation:

They say that since all men are created equal, then why should they pay heavy taxes to the British? They say that their God has given them rights such as the pursuit of happiness, life, and liberty, and since they have these rights, then they have to right to become their own nation.
