Thomas Paine's Common Sense was considered radical for several reasons.

Firstly, its arguments about taxation were new and groundbreaking. Paine argued that it was unreasonable for Britain to impose heavy taxes on the American colonies without giving them proper representation in the British parliament. This idea challenged the traditional system of colonial rule and the belief in British authority.

Secondly, Paine's rejection of the monarchy was controversial for the time. Common Sense criticized the institution of monarchy, arguing that hereditary rule was inherently flawed and that power should be vested in the people. This was a radical departure from the prevailing belief in the divine right of kings.

Furthermore, Paine's ideas about religion were controversial for the era. He questioned the authority and legitimacy of organized religion, advocating for a more rational and individualistic approach to spirituality. This challenged the dominant religious beliefs and practices of the time.

Lastly, Common Sense opposed republicanism, which was strongly supported by many Patriots and influential figures in the American colonies. Paine argued for complete independence from Britain and the creation of a democratic government, which went against the more moderate views of some colonial leaders who initially sought reconciliation with Britain.

Overall, Thomas Paine's Common Sense was seen as radical because it challenged traditional systems of government, questioned religious authority, and advocated for a complete break from British rule. Its ideas were revolutionary and had a significant impact on shaping public opinion and the American Revolution.
