A Loyalist could respond to the Patriots' arguments against British taxation by saying it was justified and needed.
Before Great Britain started to tax the colonists, they had practiced salutary neglect. This was a good type of neglect and let the colonists deal with matters on their own, without British interference. Great Britain only cared about the colonies making money for them, so they left them alone for the most part.
This changed when the French and Indian War ended, as Great Britain needed to pay for the very expensive war. This was when they stopped practicing salutary neglect and started to tax the colonists. The French and Indian war was fought on the soil of the colonists and Loyalists argued that it was fought in order to protect the colonies, so it was fair that Great Britain was taxing them.
Even after the French and Indian War, Great Britain assigned troops to protect the colonists from outsiders. They also used this as a way to justify them taxing the colonists, which Loyalists deemed to protect and help the colonists.
