East India Tea was attempt to monopolize the tea sales. Taxation was not part of this problem. They would have attempted to reduce taxation if they could have maintained
their preeminence.

Loyalists and non-loyalists abounded in those days. There were those who supported the King and his monopolistic practices.

It wasn't about taxation but about maintaining political power through the manipulation of sales of tea. Therefore, Carol is correct. Corporate power influences Parliament as it does Congress in the US today.

The fact that the Colonists had no tea of their own is false. They were able to develop private tea businesses that conflicted with Mother England's monopoly. Hence, The Boston Tea Party.

As to the notion of "centrist" as moderate, this concept is distorted. There are no centrists but those leaning in one direction or another. Moderation is a myth.
Witness the Blue Dog Dems and tell us that this is moderation.
