This is in the town next to me. My son recently wore a MAGA hat on a school field trip (8th grade). One of the lib teachers gave him a hard time about it, but they let him wear it.
I went to Plymouth State in the 1980s! I have many friends in NH... LOVE THIS STATE!!
I lived in Epping for 14 years but my kids went to St. Thomas Aquinas. We did go to the budget meetings every year and that was enough interaction with the teachers to know we never wanted our kids to go there. It turned out that we transferred to Georgia before we had to worry about it.
Epping is fairly rural too, but I guess too close to the Masshole influence.
