This. They wouldn't certainly not be accepted by travellers but let's not forget about the squatting community
I spent about 1.5 years in a well organized squat in london in my late teens and there were many people with children who were part of alternative lifestyles and in this case, i could imagine some anti- establishment sorts helping the family to lay low for a time, but ehile i doubt that would last this long, i could certainly see it working for them in the past.
There is also no shortage of squats and squat-able places, ways to access heat and electricity and have a somewhat comfortable place to live for a time.
I imagine at this point, given the coverage they have received, they are keeping to themselves and if they was any interaction with people, it would be strictly with those who have the same views of gov't institutions and authority as they do.
But if it was simply that, there would be no fuss. Imho there is more to the story.
