Sorry, but they most certainly did. Not to the same extent as the Loyalists, perhaps, but the extent was certainly not "zero". Unless you classify "tarring and feathering" as light entertainment.
My paternal family got here in 1633, one ancestor signed the Declaration of Independence, family members fought in the Revolutionary War, and one served in Washington's cabinet, so I have more than passing interest in the colonial and post-colonial period of history.
