What's wrong with it is that I can't vote for anyone that I share some views that are important to me with, unlike in Sweden, Denmark, Norway, Spain, France, Portugal, Germany, etc. I'm forced into choosing between two parties which both propose many of the same things that I oppose. Whether they are colluding or not, they're identical on many policies that many people oppose and there is no alternative. On your second point, you assume there are an equal number of tribalists without any data on that. It's beside the point anyway.
