I just know I'll be sorry for looking down this rabbit hole, but hey ho...
I happen to have actual experience (ie, not my mate down the pub; or some bloke off a forum) of travellers/gypsy communities. They came to my school(s), a few set down roots, mainly transient. The adults fell between two camps: education is not needed for our lifestyle; or, our kids need education to adjust to a changing world. The adults, while sometimes presenting as 'aggressive', were universally polite to me and my staff, at least to my face! On the whole I liked their kids, who did reasonably well with us.
But here's the thing... they never did themselves any favours. When they left anywhere, it needed cleaning with bulldozers! Pop-up camps more so, but the permanent camps too. If they had, a simple lifestyle 'on the land and byways', they certainly didn't respect the two when they moved. In Ireland, where most of mine came from, they are absolutely hated, for the same and worse. None ever did me wrong.
But you have to help yourself, it seems to me, and they don't seem to.
