There has been a lot of talk from the described "centrists" and those who are turned off by how "divisive and heated" politics has gotten in the U.S. in the last couple of years.
Why can't things be like they used to be? Why can't we be sensible and just come together?
What they are actually witnessing is the death of the center. For years people have kept quiet about their actual interests and issues they had with their country/culture. However, this is changing. The tribalism rooted deeply within every person on earth is emerging to the surface and they are finally standing for what they actually believe in and no longer have interest in singing kumbaya.
This isn't a bad thing. People naturally self-segregate whether they want to admit it or not. Some groups just don't get along with others. You can't seriously expect ancaps and libsocs to get along and want to spend extended periods of time with each other, can you?
What the final solution the fracturing of american political discourse will be is unclear to me at this time, but a solution should be found soon, to minimize the damage of whatever conflict is just on the horizon.
