What was the colonists biggest complaint about the Townshend Acts?

The colonists' biggest complaint about the Townshend Acts was that they imposed taxes on essential goods, such as tea, glass, and paint, without their consent. They argued that this was a violation of their rights as English subjects, as they had no representation in Parliament. The slogan "no taxation without representation" encapsulated their discontent, leading to widespread protests and boycotts against British goods. Ultimately, the Townshend Acts intensified colonial resentment towards British rule.
