I have thought something similar; but, in terms of Left and Right. We are at a point in this country where we simply have strayed so far from any commonality with one another, that perhaps we should consider a break. Blue policies vs. Red policies -- that way, everyone can live according to their liking of how things should be run in any particular state.
“I have thought something similar; but, in terms of Left and Right.”
No question that’s a problem as well - in fact it’s probably the bigger problem. Most blacks are agitated by white liberals. ACORN, BLM, White Privilege, were all started by whites.
If you want a reasonably peaceful country, there has to be a dominant culture and a fairly homogeneous population.
In fact a nation-state should be looked at as a container (with a protected border) of a dominant culture with a homogeneous population. The latter is not as important if the average abilities of the various groups are roughly the same. For example I can see asians and whites living fairy peacefuly together. Whereas white and blacks or asians and blacks would have more discords because of the significant difference in the AVERAGE IQ of the groups in question.
