Water usage is probably my biggest. Living in a high desert, my wife and MIL see no problem with filling one side of the sink with hot soapy water to wash a few dishes because “that’s just how I’ve always done it”, to watering the grass and plants for hours. All of this makes me mental.
I don’t think that will happen given the strongly held beliefs each side has as well as the polarization in this country.
It also does not help that there are politicians and news organizations out there that are happy to throw more fuel on the fire, driving a wedge deeper between two groups.
