Kerrville and that area are going through it right now and so maybe their politics keeps you from moving there, that's your bad, not theirs. Basing your whereabouts on your neighbor's political views is taxing and is unnecessary.
I move around year to year, mostly small city's and big towns (how do we classify this?) El Paso, New Braunsfels, Galveston, San Antonio, Austin and am currently in Uvalde. Every place has been great and every place has their shit you deal with.
Out of all of them, id say Uvalde has been my favorite, and that as we know is my personal preference.
I'd live in Kerrville, Hunt, Kerr County in a drop of a hat. If the company I l work for said we need you in Kerrville, id say it better be for more than a year!
Outside of the metro areas, its all conservative and there's a reason for that. Im sure some are militant, as you describe wanting to avoid, but 97% are not. Small town living is simple and there's plenty of space.
