I very much agree with your response, the implication of the two party system, and the notion of the wedge issue and its inability to be solved. What makes this more painful now is seemingly every issue being discussed is now a wedge issue (immigration, education, healthcare, taxes, abortion, budget, etc) which has inhibited all progress.
It seems like making others aware of how much the two party system is harming societal progress is important, so we can start making decisions to inch us closer to where we want to be, rather than continuing to fall victim to the status quo.
