TRANSPARENCY BEHIND CLOSED DOORS - One Party Involvement Is NOT Bi-Partisan

When the final vote is taken on the unwanted Obamacare bill, it will be behind closed doors and Republicans will be excluded from the process. It seems to me that excluding either party from a vote usurps our "representation"... such as it is.

At the beginning of the first American Revolution it was proclaimed that "Taxation without representation is tyranny!" Inasmuch as Obamacare will be funded with our tax dollars, and subsequent increases therein, it logically follows that eliminating the Republican party from the process is tyranny! A large percentage of the population is being denied their representation on a tax-dependent issue. If, by design, we do not have full and complete representation, during the process of debate over a bill that will increase our taxes if passed, then we are faced with an act of tyranny.
Or... is there something I don't understand about how a unilateral, partisan government action - one that forces unwanted additional taxes upon its people to support programs which the majority of those people do not want - escapes the definition of tyranny?

DEMAND FULL AND COMPLETE REPRESENTATION DURING THE FINAL VOTE ON OBAMACARE!
