Why did the stamp act cause such a furor in the colonies?

The Stamp Act was actually a tax to help Britain pay the war damages after the French and Indian War, it put a tax on paper items like documents and newspapers. The British said this was justifiable since they were protecting the colonists, which was true to an extent, but the colonists felt like this was not fair. The main problem was they had no representation in British Parliament, so they had no say in what was going on, including being what they were being taxed on and how much. This is called "taxation without representation", which was a continuous problem among the British and the colonists. The Stamp Act made many colonists end up boycotting certain products and revolting.
